Most rogue abilities are slightly gear dependant, and evis is not at all gear dependant.
A rogue can still crit for 1.5k with evis, and backstabs can easily reach crits of 700 aswell, with a crap dagger.
Besides, he's killing PvEing gold farmers, would love to see him do the same thing in Alterac, see if he survives from the hardcore PvP guys.
It'd be the same as giving a baby or a person with no expierence at all with guns a machine gun (and thus not knowing how to shoot it), then stab him to death.
Yes, he was good, and I've seen worse people. But the fact still remains if they made eviserate dependent on weapon, and not just damage in itself, then that would fix the problem, and fix the problem of outdated damage on eviserate.
No, I'm saying it would fix the problem of him using a lvl 1 dagger and killing people, scale damage to weapon, fixing that and fixing outdated damage at later levels.
