How come slashing burst doesnt have any restictions to how much u can spam it? like blink uses alot more mp within 30secs, and also as a cooldown on it, combine shoulderdash to the slashing burst and warrs can just use these 2 skills to move about and never get hit in pvp. Also allowing warrs to get tower mega easy, where if wizz or tao get stuck they need to kill.

Not saying it needs changing, just asking why is it like this?
If its supposed to be like this, should be a skill for taos to get out of met/blizz, like warrs n wizzies have
