arlock - Imp/Felhunter/Voidwalker warlocks have always been trivial for hemo specs, simply stun lock them to death and use COS to fill the gap between stun locks. Against felhunter you may need to sprint in or uses vanish to get improved stealth to get the opener. Succubus warlocks are beaten in so many ways with COS to buy runescape gold, trinket seduce and blind warlock then COS the next seduce to kill succubus about cheap runescape gold.
Heck if they are not soul link you can kill them during Premed CS evis GS, COS the incoming seduce, unload renataki and they are already done. Felguard warlock can use intercept to break your stun lock, so COS the incoming coil/DOT then get back in his face with evasion. There really is not much a warlock can do outside of possibly engineering or tidal charm. In that case just prep for a second set of timers, we are finally true warlock counter to buy runescape gold.
In BGs without COS they are absolutely positively a nightmare to deal with peaking of warlocks. This is why I will never give up COS. You know how it is, you fighting someone then a warlock comes out of nowhere and DOTs you up. The 3-4 DOTs (depend on their build) alone is enough to kill you about cheap runescape gold. They never have to cast anything else. I absolutely love AV where I get 8+ DOTs yet I clear them all in one shot and sprints into safety.
It will greatly increase our survivability coming out of a freezing trap or in group PVP against hunters. Blind is also potentially affected by this ability as it is most likely considered a ranged attack to buy runescape gold. If you only have +3% to hit from gear, and have 5 point in precision (+5 to hit in melee), you can still miss a blind. This is why I think evasion will be useful against rogues as well.
