Oh that thing where you don't read the post, but respond anyway. Super. Forums are to not read stuff I think.
You know what was better than rogue + OP class? OP class + OP class.

Anyway, to address the topic again:
I think that the evasion buff will be solid because pretty much every other cooldown like this has similar design in the modern day. Evasion is pretty easily countered- not only do spells go through it as you would expect, but the myraid of talent CC all is off the melee hit table- even ones that didn't used to be, like the druid stun. It will also fix this:
"Somerogue dodges Verain's Gouge"
"Verain uses evasion"
"Verain is stunned by Somerogue's Kidney shot"
I will in general welcome this, as the relatively low avoidance passively (especially combined with the high frontal avoidance on plate classes, who still have their armor) has meant that in any kind of toe to toe we end up eating a lot of damage whenever our opponent isn't controlled- and that's not MUCH more often than WE are controlled.
It's also been said that evasion is too gear dependent, and I think that's a fair complaint. If you start out with 20% avoidance, your chance to be hit during evasion is 30%. If you can up that 20% to a 30%, then you eliminate a third of incoming blows under evasion.
I also think this will be an excellent play versus hunters, whom I really thought evasion was going to prove effective against when we were able to dodge ranged attacks- but in practice, I get chewed up pretty hard anyway, being pretty healthirsty even with evasion active, with a bunch of stunnypets behind me and whatever. A full 100% should really help during the uncontrolled portion of that, and definitely versus that ridiculous unbreakable webflareroot.
