It is what 5 months after release, and instant abilities still bug on use about 50% of the time -> only animation goes trough, no dmg/cooldown/effect etc .
I will be buying gw2, and play both games, but if this major bug is not fixed, the free month will be my last. I can not stand it, combat responsiveness is bad enough with crappy game engine, i mean even when you "DIE" it takes 2 seconds from when you actually get killed until character re-spawn in start area-> until respawn your character is just stunned, But playing russian roulette every time you use an ability, will it do something or not?, its the end of me.
