Im a rogue on zek as well. I dont think that still using 2.0 at level 80 is much of a handicap. I have the FC aug as well as tunat aug making it 30 19 which isnt too bad.
Also, on zek, Waylay and jugular slash can be used in pvp when ever they are up. This is SO amazingly helpful and almost balances out the fact that we dont have 50 damage pokers yet.
I have jugular slash, disarm, and waylay all tethered to my backstab key , so when i backstab, my opponent gets stunned ( for a good while ), dotted, and sometimes disarmed.
When stun lands i pop ligament slice and if it lands then you are in the clearing and they will be dead in under 10 seconds
Or if your quick enough you can stun, pop fury/frenzy and tear them apart before they can escape to the pok book or w/e :P
