Word on the forums was that if you grabbed the new FP at the STV Rebel Camp and flew to Booty Bay, you'd cross directly over the Gurubashi Arena and get flagged if you weren't already. The fun thing is that apparantly you could be attacked by Alliance too, once you landed in BB. Of course we ran through Duskwood to test it - who doesn't want to kill their own guildies once in a while? - but sadly it didn't work for us. Might be a PvE realm thing, since we're always flagged in STV and thus nothing changes for us when flying over the Arena. For those of you on PvE realms, did you test it out and go Alliance killing? And if you did, how did the guards react to it?
Besides that slight dissappointment in what could be a super fun glitch, I'm very happy with 2.3. I don't like that the Wintersaber rep gain is so much easier, but hey, at least I'll get my purple kitty sooner than expected. I'm also very happy with the auto-leave-shadowform when I hit a holy spell. It's gonna cut down that precious GCD second during PvP which might save my sorry ass every now and then! Noticed also that quests you haven't yet picked up show up on the minimap now. That comes off as a wee bit lazy to me, but hey, whatever.
Beyond that I haven't really tested things out yet. Haven't even bothered to pick up Fear Ward. I went straight to Winterspring this morning and I plan to stay here until we head for Zul'Aman tonight (provided that the server lives). There's already another Priest grinding Wintersaber rep and I expect there'll be several more as the days go by. I want to finish asap to avoid the crowd :[
ETA: ding! Revered.
