Jeez there's so many things...
*Not being able to run and grab ropes/ladders
*Insane lag when other people get on my map while i'm trying to lvl sometimes or when i'm in an instance with a few people
*When the game just decides to freeze when you're in the middle of battle and when it decides to resume it just fastforwards to your death
*People vending stuff for way more than their worth
*The low drop rate on instance armor and equip
. i mean i shouldn't be coming out of an instance empty handed if i just ran the whole thing..
