i spent just 30mn on my orb sorc for now on, i was able to clear a2 a3 new bosses (while dying a bit), and i did some a5 red portal to test. i just couldnt kill Ifrit. tried some inf cow but real quick in 15 player game, was laking dmg.
it felt OKish, i hope if i spend more time on it i ll be able to balance the char and make it tanky enough but with serious dmg.
This orbsorc i tested is 11k orb/ 30k'ish blizz for now. i need new storm and new shako for more tests, coz i dont wanna put my cold chants on the wrong items

edit: i enchanted 7 times only for now
