Well I setup CM differently since I found a post on the forums, if you put nova on right click you can just keep it pressed, along with diamond skin and explosive blast on keyboard, and the only key you have to mash is the tornado thingie so it's a lot less annoying like that. It's extremely efficient at clearing shit so that's cool. I used Spirit Blades while leveling, basically from the moment I unlocked it till inferno when I changed build, it seems like the best signature due to the high damage, and I used meteor most of the time with a switch to blizzard+hydra near the end cause meteor became redundant when I bought a 1k DPS 2H at lvl 52 and mobs would die to one or two ticks of blizzard on Hell 2.
There's a mp10 spirit blade build but it's very very gear dependant, it's just spiritblades plus a bunch of passives and illusionist+all the illusionist spells, so whenever you get crushed in melee you can pop teleport fracture, mirror image and time warp and keep leeching. Looks pretty fun but you need a really high DPS black weapon and a bunch of shit, didn't seem worth it to me.
Anyway just gonna farm the mobs for the hellfire shit since I can clear them pretty fast, gonna probably get me to paragon 20 or so before I'm done, then I think I'll consider leveling another char until PTR. Not that much else to play for now, march is pretty far and until then it's kinda shitty on game releases unless they release the PTR or I get invited to Wildstar or RoS beta.
