First off great thread. To the OP I can agree with most of your post. I havn't been playing as long as some of you, but i'm clocking in at 16 months. I think that's long enough to of noticed a change in the direction GW is heading, so I will post my personal experience with GW in this topic.
*Read this wall of text at your own risk*
When I first started playing, I had no idea what I was getting myself into. I had heard of the game before, but it was the level 20 cap that kept me from getting it. I admit sometimes I like grind, but I had played so many games, even up until now, that were based around it. "Grind to this level to be effective in this area, or wear this armor", and so on. Every MMO I played seemed like the same cake with different icing to me. So I decided out of pure boredom to give GW a shot.
When I first logged in and entered pre-searing, I was amazed. There were people just hanging out joking around and having fun, other people were looking for somebody for the rez sig quest, and the other one where you needed somebody to open a gate. It was an all around friendly atmosphere. Well for me anyway. I was also amazed that this game actualy had a story, rather then just being a grindfest based off of a story you would only know about by looking at the website or something.
As I made my way through Tyria, I remember thinking to myself how great it was. I joined groups, and we all worked together to accomplish the mission or quest, and "usualy" the groups I was in weren't full of bickering or build paranoia.
It wasn't long after when Factions was released. I had made it to the Ember Light Camp. Even though I told myself I would finish prophecies before I bought factions I just couldn't resist buying it and trying it out. At first it was kind of the same for me as before because not many people were used to the new professions yet. Once people did start getting used to them though I did start to notice a decline in "fun" PuG's.
After a month or two, I started finding it a lot harder to find a group because of the professions I was. The only one that didn't have a hard time was a monk I had and maybe my warrior. I do not know why this decline in what was acceptable started happening, but it did. So I found myself grouping with people that were either,
1: Professions that people didn't want.
2: Kind people that didn't really care or were willing to offer build suggestions.
3: People who were just desperate to get through the missions and move on.
Now 1 is kind of a double edged sword for me. It sucked that some professions were just pushed to the side, however it was awesome when we beat the missions with a group full of outcasts.
Anyway to fastforward a bit, Nightfall. I was very excited about this campaign. I had been following it since I learned of it's exsitence. To be honest I loved the story, but hated the enviroments as most of it was desert. I mean they looked good, but the theme just seemed to carry on. It was the story and some of the new monsters that kept me going. NF was bad for PuG's in my opinion though. I do like heros, and at times i'm thankful for them, but they kind of took the MMO out of this MMO. I'm not saying it's not possible to find a group, it just seems to be harder to organize one.
Now with NF and the SS/LB titles. I actualy liked them. I didn't mind an extra boost against margonites, and the later released pve only skills. Some of them looked cool, but were in no way mandatory. I'm sorry for those of you who couldn't find groups because you were not rank 5 or above LB, I didn't have that problem though. I'm sure cookie cutter mentality exsited long before NF, but I didn't really see "much" of problem until DOA with the exception of the x tanks, x nukers, MM, 2 monks thing in Factions.
After nightfall I had gotten burned out and took a small break. When I came back I made a few new characters, and had fun again. I learned of GW:EN and spent most of my time LB/SS farming in wurms to make some cash, and get title points. Bad move on my part. That last month before GW:EN it's pretty much all I did. It was nice when I got something nice from a drop, but I was bored out of my skull. That's my own fault though for doing something I didn't enjoy. I felt like I needed to though for these new armors I might want. It was a long shot though because at the time I had no idea what the armors would look like.
The more I read about GW:EN, and the more videos I watched, I grew more excited. I was very happy to see the return of "skill rewards" in quests, new armor, and mostly, dungeons or rather content with rewards worthy of lvl 20 characters. I will say this about GW:EN, I enjoyed the story, and the enviroments, even with the reused rooms in dungeons. I was kind of shocked though to find out about the needing ranks to craft weapons and armor though. I was also dissapointed in the drops for GW:EN.
I mean for some of us saving up the money and materials is a grind all in its own. I'm not complaining, for a story element I can see it, from a different, more game play perspective though I think it's kind of ridiculous. I did it though on one of my rits. I got the norn armor. I'm very happy with it to. However I can't really see trying to do the same on several of my other characters. I guess if I had been more patient while getting that armor for one of my rits, I could of got it with pretty much no grind at all since it was Norn. However it would of been game over, what campaign would you like to repeat?
As for the PVE skills, well I like them. I don't find most of them that great, but that's my opinion, and I can accept the fact that other people will find ways to use them that I won't think of and so on. However it's yet another reason to grind. I'm kind of mixed on the issue of them being tied to a title track. So I won't try to debate here.
I guess my number 1 disappointment with GW:EN is my fault. I figured I would feel refreshed with the game I was playing. I did, for a few hours. Once the newness wore off I felt like I was just playing once again, "the same cake with different icing" for GW. I'm actualy hoping for GW2 they blow our house down with something that makes the game feel refreshing again. I don't want a WOW knock off, but I don't want a GW1.2 either.
I could go on but this is way to long already. I'll end on titles in a brief kind of way. I love cartography because it helps you keep track of what you have explored. It's like in a FPS that keeps track of how many headshots you've had. I like these kind of titles. Some of these other titles, like lucky, and unlucky I find very stupid. That's all AFK on a ring for a few nights and see what happens!!! No thanks.
To end this, I still do enjoy Guild Wars, and don't want to go back to the typical MMO crap i've played before. So that is why I care, and the "go play something else" line isn't my "Alem's Remedy".
