A few good spots
70-73 - There is 4 little ditches around Galakdrond's Rest in Dragonblight. You can pull 8 mobs, melee scourge, and theres usually a caster in the group but I don't find him too bad. Takes a little practice getting all 8 not to evade on you, but its a good spot to work on your fast roundup technique. The respawn times are absolutely incredible, you really only need to work with 2 of these 4 ditches and you can go for hours on end. Past about ~72-73 I'd move on to better spots for more XP/hour though. It kind of stinks being limitted to pulls of 8 mobs, but the respawn time makes it worth it.
71-74 - Scarlet camp, north of Naxxramus in Dragonblight. Great spot, absolutely amazing. Pulling groups of 12-15 is quite possible here. There are 5 camps, with a few pats on the road that you want to drag into a 12 pull. Spend about an hour here, you learn the rotations. Can get a little packed at times =( Still my favorite spot I found so far, I held a steady 430k XP/hour all the way from 74-75 (about 3.5 hours to level, no rest XP).
72-76 - The Suntouched Pillar in Sholazar Basin. I did a bit of grinding here at 73 (mobs were 75-76) and it worked out well since I have good +hit and plenty of damage. Rounded up less mobs, can't pull 12-15 like you can at Scarlet camp, but since they were giving more XP it sort of balanced out. At 73 I was getting about 1200xp/kill non rested, and pulling 8 each time. Less competition too, I'll keep this as a backup spot. Got my heavy frostweave bandage book here :P
I need to find zones past ~76-78. I talked to a few mages on the o-boards about AoE grinding and they mentioned a few places in Ice Crown I'll check out.
I like all the BOE greens and frostweave I get while AoE grinding. So if anyone knows other good spots (melee mobs, packed tight, fast respawns), preferably 76+ let me know :P
Regarding the new talents, love em. Shattered barrier, chilled to the bone, my blizzard is snaring for 85% and it crits now. 2 blizzards drops a group of even level mobs in my gear, love it so much.
