there is one actually, go t heart of sin, rush to azmodan, then rush to iskatu.
restart. but i think people would prefer the snakes at khazim outpost to level up. Only thing is getting to that part is though.

Playing with my fiancee's 52 wiz. I don't play wiz so I newb lol, maybe a more pro wiz might kill the mobs much quicker and so the 2.7mil exp/hour figure could increase.

did Zoltul, act 2 black soul stone, nightmare. for more then 8hours(forgot how many) but lvl up from 50 to 56. I think was pulling 1.5minute per run for 36kexp.

Earned close to 400k gold from vendoring blues and quest rewards, plus dropped gold. It is not much gold, but it is hard earned gold. I know AH can make few hundred k per 10minute but thats that.
note: wasted 1-2 hour trying to do the wortham doom in hell mode and fail miserably. Knockback, XXX, ... mob totally pwned me bad.
I switch back to the tried and true 36k, and was able to get 55-56 bang out in 1 and half hr.

Gonna have to try Iskatu if blzzard didnt patch it up. Just bought a 300++ dps 1h axe. hopefully can grind all the way to 60 tomorrow.
