Hi, I am still quite new to the class and after playing mdps classes such as a DK/paladin/warrior I find it kinda odd that rogue has to wait his energy to fill up for a while before using any ability. What I mean by this is that after the initial burst phase (of the assasination spec) you will generally need to wait 1-2 seconds before using mutilate, after you've used a 4/5CP Envenom. That doesn't always happen with the 51/13/8 spec, but still, I find it weird that there's a class with a spec that has to wait for so long to use an ability.
The prio-rotation I use is:
1. Stealth
2. Bleed effect ability/Ambush
3. SnD + engi gloves
4. HfB
5. Mutilate until 4/5 CP then Envenom.
repeat until overkill is over, vanish, reenter combat and doing the same from 5.
TL;DR: My question is, is there anything wrong with the way rogue energy regen works, or is it just my imagination/bad prio-rotation?
note: I haven't found any bugtracker reports that would answer this.
