I'm not having a problem with lag, so I can't complain about that, but there's a bunch I would have liked to be different:
-I agree, guilds are kinda pointless right now. I mean, If you're not friends anyways, you can't even tell who's on besides typing "Who's on" in guild chat. (It reminds me of way back when I first got AOL 2.0, when you had IM, but no buddy list , so you'd be like "you on?" and if you got no response, they weren't. But I digress.

)
-I want more non-story quests! There's like 5 or something, and they all have pathetic rewards now that I'm at a mid-high level.
-Maybe not classes, but
some way of customizing your character would be nice. Maybe different choices on weapons like lvl 1: axe or sword, lvl 5 gun or voodoo, etc. Right now, replay value=0.
-Changing costumes! I thought that we would be able to change costumes, get hook hands, peg legs, etc... as we leveled up. As it is, the starting costume options are pathetic. (Maybe it's because I'm coming from City of Heroes, where you are just
spoiled for costumes.
-Can you say /lfg?
-Better quests! After the 10th "go to Doc Grog" or "get 15 crab biles" quest, I get tired of it! Put some original thinking into the quests people!
Sorry for the rant...
I'm sure there's more that I don't like, but I can't think of it right now. Unless one or more of these resquests is filled, I'm canceling before the first month is through. It's all so... repetative. I don't know about you, but the fun factor is diminishing for me and Pirates of the Burning Sea is coming out in January.
