Well, I did some reps for profession recipes - priest needed enchanting and tailoring, paladin needed the belt buckle etc. The priest got the worst end of the deal, and that was the bag and enchanting recipes from shado-pan and august celestials. I bitched about it before but going from golden lotus revered THEN to revered/exalted with the two of them was bollocks.
My hunter just recently got a lot of insignias, just to be able to get into the LFRs. My bad luck streak is legendary; talk to anyone from my old raiding guilds and they'll tell you how fucking awful it was. It continues, so when I wanted to gear my hunter up a bit, I started doing heroics but couldn't get shit to drop. Literally. I'd do heroics where every boss had a chance to drop 1-2 items and none would. Over and over again. I crafted some items to boost ilvl, and did heroics, and eventually went "fuck it". The justice point items are not high enough ilvl for 460 LFRs, unless you have other items that are much higher. So, my bad luck streak going, I ended up sucking down insignias to get the free 489 ring from klaxxi and the 489 neck from golden lotus, and then spent the VP I got from dailies on items from the two of those factions.
The whole way to grind gear in this expansion is just super frustrating; if you get unlucky you're pretty fucked I feel, whereas other expansions it seemed you had a better avenue. I'm not against the ilvl requirement for the LFRs, but no requirement back in the day meant if I got fucked on drops prior I might not get fucked on drops NOW.
Meh. I got her into LFR and she's at about 479 ilvl. I imagine I'll get a few more items next week and be able to hop into ToT LFR.
Also remember, that the shado-pan assault rep can only be gotten from specific things like scenarios and the raid itself - and if you don't have a high enough ilvl to do the TOT LFR, yea. You'll be sitting on neutral/friendly for awhile. Kirin Tor Offensive has nothing specifically amazing; a couple items from 476-496 that you still need to grind anyways, and none of those are the 522 ilvl.
So either way, you're grinding something technically old. Kirin Tor might be a new rep, but the ilvls are not on par with the new crap.
