First of, if yer Alliance and run BGs in the Whirlwind group and needs some more resilience, go away. Nuthin' fer you here. Urthona, I'm looking at you. Sonvar, probably not so much.
Okies, now that they's gone, here's some info what ya may have missed in all the other 2.4 excitements. For each class there be a new set of armor specifically for the PvPing. Is blues, so not all fancy and purple and with the glowing shoulders like the gladiator's kit, BUT it don't cost no honor points or marks anything, just gold. Deal is, there's five quartermasters in Outland, each'll sell ya one piece fer just a few gold pieces, as long as you be honored with they's faction. Poof! Instant PvP gear, with resilience and all, good-to-go. Which quartermasters? Is Sha'tar and Lower City and Keepers of Time and two others what I can't be bothered to remember the details. Maybe Sporeggar. I dunno - look it up fer yerself, already.
So, how good is this stuff? Well, is best I can tell is exactly the same as the Grand Marshall / High Warlord gear ya used to be able to get. Nifty thing is, with two pieces ya get a +35 resilience bonus, what stacks with the one ya get from two pieces of Gladiator's. Whoa. So what I done is picked up new legs and a chestpiece, which I'd been using old PvE gear for, and now me resilience is a respectable 255 (were 194 before). Long way from the zero I started with. So anyways, if yer just gettin' going in the BGs, ya owe it to yerself to check these out. Is all can be found on this page - I's too lazy fer to write out all them different sets.
Okay, someone tell them Alliance buggers they can come back in now.
