I've never seen so many Strawman arguments in a single thread before... wow.
Anyway, I had descided to not buy Factions due to it's content. I felt it didn't have enough content I would enjoy for my money. A week after it's release I finally caved in (I so wanted to play an Assassin) and picked it up. A week later, I finished the story line. I didn't rush through it, it was just done. I was like... wow. That was it?
For the OP, my reasons for really being disappointed (these are my opinions; any flaming or attempts to alter my opinions will result in /yawn - don't like or agree with what I say? Cool with me. This is not whining or an argument, it's opinion.):
The farming. Farming is so boring, so dull and feels like "work". Faction points are needed in such a huge quantity and are so boring to come by.
The Challenge missions are horrible. They are dull beyond belief after you've done it several times. You go the same route over and over and over and over... /bored
The Competitive missions are so empty. I sat in Aspenwood watching the counter reset for 30min just trying to find another way to farm faction points... At least allow people to enter vs the AI in these so we can play the game. Sitting there is /bored.
GLF "Cookie Cutter builds" for FF! OMG, I thought I had gotten away from this in quiting EQ. Sitting around for 30 minutes to an hour "X/X LFG" gets old so fast. Doesn't matter what class combo you are, if you don't fit into some mold, forget it. /bored.
Now with the above said, I know some one is bound to say "Well, did you unlock all the map?" or "Did you get all the elites unlocked?" - sorry, titles are not a goal of mine. If I gain a title it will be through playing, not because of working for it.
What I did like about Factions: The difficulty. First time I got popped with Dragon Stomp I was awe inspired. After a quick rez at the shrine I ran back with a grin on my face to go pay my respects to that ele. I dashed to him only to get leveled by the Knight and his nasty axe. I laughed so hard... now that I loved.
Oni. I love those things. Awesome. Really cause a moment of "Eeeep!" when they spawn right on you while you are fighting something else.
Jade Sea and Echovald Forest = really cool areas. Just wish there were more missions (not quests) in those areas.
No solo players. I like the need to group with others, but this is a double edged sword when nitwits demand you play "their" game (ie, cookie cutter builds). When I come across people like that, I always tell them I want them to change thier build so it will work with mine better. They 100% leave the group or kick me out of thiers.
But those good things are crushed under the farming and boredom factors.
Sum: Anet got Factions backwards. Less quests and more Missions. Drops and rewards are backwards. After level 20 you don't need more exp, you need more gold. You still get skill points (my Assassin has 80 now and I've bought all skills for primary and secondary - two secondaries actually) so why the exp?
As I said, this is my opinion, flame if you desire, I've got steaks needing to be cooked.
