I have a 50 assassin and a 27 sorc,
Leveled as deception was really fun kinda like a rogue with the improved stealth and backstab but still having some ranged when you need it.
with 2 of your burst abilities are 10 yard range and spamable slow you are hard to run from.
At 50 ive respecced darkness for pvp guard is very useful and you have way more survivability while still maintaining a good amount of burst if you gear correctly.
I dont have enough talent points for the hybrid spec yet on my sorc i just finished the 1/2 madness tree
So far very fun you have dots, channeled lightning with no cd, shock and procs for no cast time crushing darkness so lots of mobility with a constant 30 yard range in pvp
Really thats what it comes down to in play style is ranged vs melee since as a assassin you have no consistent 10+ yard abilities
side note on my assassin i am biochem so having a big heal with 90 sec cd might skew how I feel on its power sad the resuables will be phased out =(
