Resistance needs to be modified. Just the other day a couple players got into an argument over resistances because one higher lvl was checking on lowbies to make sure they were getting theirs up for later.
This is how it goes, rogues and some of the scouts dodge attacks, the other scouts and warriors block attacks, mages and priests shield themselves with magic of one kind. As it has been said before resistances account for too much of the game play.
A single person that can max all of them can easily solo most anything leaving there to be difficulty in finding things to do. Make there be some challenge to playing instead of the relentless grind that drives people away constantly. Custom equipment should more of a want than a necessity.
Team oriented areas: I like it, I like level restrictions, and I like the no camping idea, possibly some other way of doing it though.
I present the idea of creating a voting system that rewards players for voting everyday with some kind of token or a random amount and type of quest tokens for voting everyday. Not sure how to do it, but I know WoW private servers do this to encourage people to vote everyday and as often as permitted.
(Edit 5/24/10) I was thinking last night while at work watching the blue collar comedy tour for the umtenth time this month and realized something, after you get all your customs, all stats are equal unless your human. I believe each race should have that one stat that they naturally excel in and get a bonus for later, even a point or two can make a big difference. Of course, humans wouldn't get crap, because well, they are humans.
There are my ideas and my opinions.
