In NA the "normal" amount of agility is 9-15 where as in EU that is 15-21. Without a good balance this couldn't have happened. Don't start argue with the specific numbers, you get the point.
IMO the thing we need the most is a new xp/gold system.
That's for sure. I've been called an agi whore on an alt when I had 21 agi. Made me lol.
While I agree with some of your suggestions Joker, I dislike the idea of a wealth skill or buffing the lvl cap just to compensate for adding in the wealth skill.
I'd be for iupping the lvl cap I suppose but it'd be easier just to increase the game speed rather than force people to lvl up more to compensate for a slower game.
I'm definitely for conquest mode but instead of killing battle, just get rid of siege instead.
