okay, so at 36 i left SM to go try sunken temple. Just finding your way to zone in is a total nightmare.
regardless, at 36 i was getting a level about every 20 minutes which was a clear of all 3 wings (cath, armory, library+cath againish) It takes me dead on 15 minutes to clear the 3 areas. I was getting about 110 xp per mob.
In sunken temple i did that strat where i left my guys on zone in, cleared 2 rings below and also the dragon circle, took me about 10 minutes after i had done it a few times, at best you could get to 8 minuts, but that doesn't do you any good due to lockouts. It came up to about a level every 35 minutes. I got about 160ish per mob but when you compare it to the million mob zerg in cath it just loses out.
I've done ZF in the past and it felt really slow, maybe i was doing it wrong.

I really hate having to go to 45 in SM though , specially since the mobs are 38ish i think?

if anyone knows of any other faster ways to go from 40-45 let me know
thx!
