Case in point:
I have got 53% standard resilience+ 15% all damage reduction from talent "ironhawk". It works out to abt 55%+ resilience. I got two-shot by a 163,591 Spellstorm. If one increases it by 55%, that's +89,975.
So yeah, instead of GC nerfing Rogues, perhaps you might want to take a look at your beloved "hybrid" burst. The last time a Rogue two shot me was back in 2005.
In before "You need to L2P" and "You got Outplayed".
