To get that, I had to fight the limitations of the class every step of the way and was constantly running out of energy, even during single-target burst (Operative's class role).
The Backstab nerf sucks.
The unlisted Hidden Strike knockdown nerf sucks,
The unlisted energy nerf is game-breaking and totally uncalled for.
I guess I shouldn't even post this, because Georg Zoeller will interpret it as 'teams of Operatives stunlocking people and causing them to quit the game'...
