Rogue/Warrior:
This class aoe-dmg is way too strong. Please nerf slightly 6-7%.
Rogue/Knight:
This class can tank Rofl but its only way to generate meaningful aoe-Aggro is Whitehits. Since Whitehits have an even less range than melee-skills, this results in bad crowd control. Also this class is too squishy for Dark Core.
Suggestions:
1) Make Disarmament aoe and increase its cooldown to like 5 seconds.
2) Add a % atk debuff on all targets affected by your Searing Light.
Rogue/Bard and Rogue/Scout:
These classes utilize channels like Combo-Shot and Fast Draw. This makes it harder to time Perfect Slice because you would have to purposely not use these Channels and lose damage in the short-term, if a Perfect Slice is getting ready.
Suggestions:
Change Combo-Shot and Fast Draw to be instant but add global cooldown. Since Perfect Slice ignores Global Cooldown this would be a simple fix.
