I have been sweating it out in arenas for about a month, just sucking !@# w. assassination spec. In between queues I get so mad at people telling me to change to sub that I finally do for the first time.
I take a quick glance at the abilities I have never used, or even read before, and while in the arena waiting room with the forty five seconds ticking away I unlock my action bars, arrange things into what i think might help me set an alright rotation, relock, stealth and go.
We won that match and the three following after not winning the previous 14!!!!
You might say it is luck or chance, but even in standard BG I have been schooling as opposed to merely holding my own.
You might say I am a noob or weak or whatever, but I put ALOT of effort in to tweeking my assassination rogue over the past year and sub blows it out of the water on the first day.
Why else do you only see sub rogues out there. Look around and you will be suprised.
