I finally dusted off the rogue I made during Wrath. He sat at level 10 for about a decade or so, doing absolutely nothing but clogging up my character screen. I decided that I wanted to try levelling via PvP and battlegrounds. Sure, I did a few quests here and there to get some better pieces, but mostly I've been PvPing on him. He's now level 20.
I never realized just how fun rogue PvP really is. Sneaky sneaky, sap, wander off while the Alliance players in the area start blowing their AoEs all over the place. Laugh a little to myself. Wander back, sap again. When I get someone alone, it's all manner of ridiculous fun. Now, as I'm low level, all I can really do is Warsong Gulch and Arathi Basin. Since WSG pops first every time, I've yet to get into an AB. No big deal. I'm enjoying chasing down Flag Carriers, occasionally going for the Alliance Flag when my team has them all tied up at mid, and generally being a chaotic presence in the fights.
