3.1) Reason for Drunkard: with the addition of skills that require one to be drunk to gain their full benefit, I thought it would be cool to have it be that when one gets the Max Drunkard title, one could have the option to have some way to become drunk without having to carry alcohol around with you, either by making it so that when one displays the drunkard title, it makes one drunk, or by making an item (which can be transferred between characters or obtained like a bonus item and can be replaced if dropped or trashed) that will make one’s character drunk when clicked on (another idea I had was that when one gets the Max Drunkard title, one could do quests or some sort of task or crafting or some such to obtain items like the one I mentioned above, but an item for each type of alcohol [since apparently different alcohol’s have different visual effects, so one does quests or some such to be able to be each type of drunk whenever one wants]).
To summarize the idea, the reward for getting Max Drunkard title should be the ability to get drunk (and preferably each type of drunk, witch’s brew/spiked eggnog/firewater etc) whenever for free. With that in mind, the title should be account-based, firstly because it is too expensive and too time consuming to max each of 10 characters (unless Anet wants people to buy gold and use programs to do it). Secondly, because I am getting too old to spend my time doing so. I am 21, almost 22, graduated college (almost, 1 class remaining) and will need to get a job soon, I do not have time to invest in an activity which is practically work it is so joyless.
Oh, and one other thing, it would be nice if each level of alcohol gave 1 minute towards the title. YES, I know that the first two levels are supposed to represent being buzzed and not being drunk, but come on, this is a game, it does not have to be that realistic. Besides, with the current setup, people tend to spend time teleporting between their GH and a town or just standing around carefully counting the minutes rather than just playing the game drunk.
For those who already have done more than 1 character’s drunkard title and so would complain that this would make all that for nothing... You should have had this idea and asked Anet to make it so already, or you should have stopped with one character, because seriously, no one should spend that many hours trying to max Drunkard more than once (and some would say anyone who goes for Drunkard once has no life).
3.2) Displaying the Sweet Tooth title should be made into 3 levels, first at 1,000 minutes, second at 5,000, and third at 10,000 (and perhaps for those who have done more than one character, maybe make the Max level be 15-20,000 minutes). First level would make it so that one’s characters always move 25% faster in towns and outposts, Second level 50% faster, Third level 75% faster, and if a Fourth level were added, 100% faster. And this of course would be account-based. If the differentiation would be too much of a pain to implement, then just have it be Max level = 50-100% faster movement in towns/outposts.
Why? Because some towns/outposts take waaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaay too long to move around in, so the ability to move around in town faster would be awesome (again, getting too old to spend forever running from one side of an outpost to the other to go through a portal or access storage, it is a pain).
Actually, don’t make it tied to Displaying the title, just make it so that each character always has the speed boost in towns/outposts.
Oh yes, and once Max Sweet Tooth is achieved, there would still be the benefit of using sweets that give attack and movement bonuses in Explorable areas, and it could be made so that when one achieves Max Sweet Tooth, sweets that only give movements bonuses in towns/outposts would instead grant movement and attack bonuses in explorable areas.
3.3) Party Animal should be account based, and the benefit should be that each character can fart a sparkler every so often (joking, perhaps a free and unique Everlasting Crate of Fireworks that can be recovered like a bonus item or some such? ). Drunkard and Sweet Tooth I really want to see account-based because of their potential for actual player benefit, this one it would just be nice since again I would not want to level this for each character.
Considering how many character-based grind titles there are (protector, guardian, skill hunter, vanquisher), I think that it would be completely reasonable to make the above titles account-based. Heck, I would love it if Vanquisher, Protector, Guardian, and Skill Hunter were account-based because of how much grind it would take to max them for each character, but oh well. Seriously, I think that there is plenty of grind to satisfy anyone with just the Each Campaign and PvP-based titles alone.
I also have an idea for the Cartographer titles. How about when a character has completely explored an explorable area, all of the collectors and other locations of interest are revealed for that particular explorable area. This 1) lets a player know if he/she has in fact fully explored an area, and 2) provides a useful in-game benefit for actually exploring an area.
And make the Fire Imp useable by lvl 20 players, I want to see that little guy running around with me roasting ice imps in the Far North
