Truth be told... we (operatives) can still kill pretty much anyone in 1v1 situation, but we have to use every available cooldown. You pretty much have to do this to kill equally geared opponents in 1v1: shield probe -> acid blade -> relic -> adrenal -> hidden strike -> debilitate -> backstab -> shiv -> lacerate -> corrosive dart (if you can afford) -> evasion -> cloaking screen -> adrenaline probe -> acid blade -> hidden strike -> sever tendon (talented) -> back stab -> shiv -> lacerate -> corrosive dart -> (he'll start running if still alive) -> grenade -> overload shot Note that this doesn't work against sorcerers who skill out of stun and knock you back. So they need to have it on cooldown. After that you are totally useless for 3 minutes. The other spec (lethality) gives you those screenshots with 300k+ damage in WZs, because they don't even stealth (tbh you can't stealth most of the time in WZ because you are kept in combat for so long), they just put dots on everyone and farm damage.

Seems to me this happens when you press multiple mouse buttons at once (not always though).

There is one MMO that got PVP right... Eve online.. and it's the game i will always come back when other games fail.
