To be completely honest PVP in SL doesn't take much skill. There's no real skill curve and once you reach a certain there isn't anything to improve.
Every class has their Standard sequence of skills to use. The Kinetic Resevoir timing might be the only things that can be a bit challenging.

Then there's the balancing (or not balancing).
Engineer heals with these mods are insane
Operative damage with these mods are insane
Commando with these mods...can barely survive with the nap IF the operative Lash doesn't hit.
The rest is luck in dodge. The fact that operative and engineer weapons have MORE defense than the commando exclusive weapon is a joke imo.

No I don't engineers or operatives to be nerfed 100%...just balance and even it out alittlee
