I've played every class, rogues definitely have the most utility
1. cloak+feint=two HUGE minimum cd survivability tools that no other class has. Live longer and less stress on healers
2. tricks+vanish+feint=No threat issues throughout fight and starter threat to help tanks
3. short cd interrupt
4. reliable slow that can also be aoe w/ FoK
I use these abilities on at least half the fights. No other class even comes close to that amount of utility.
