Here's a quirky CM build using disintegrate I came up with.
It seems to work pretty well (I don't have the best gear or anything, but I can take out a double champ pack with annoying affix's like relects dmg, plagued, waller, jailer, frozen etc, on MP5 pretty easily)
This build definitly takes more work to play than regular CM, but I think it's more fun.
-Disintegrate: You can use whatever rune you want with it, but I like chaos nexus b/cs it seems to have the most dmg output, plus with TF it slows alot more enemies, Convergence is also a good choice.
-Energy Twister: Wicked Wind, just to proc CM
-Teleport: again, any rune is fine, but since this is your main panic button, fracture is probably best
-Diamond Skin: Prism used to reduce cost of WW and ur lazer, as they are both expensive skills, the 7 AP reduction really helps alot.
-Farmiliar: Arcanot, the 2 AP regen is very helpful, in total you want at least 14 AP per sec. 16 is better, but the n you need a full set of Tal Rasha's
-Magic Weapon: I use BM b/cs I don't have life steal on my weapon, but if you d (2-3% is good enough) then you ca switch to Conduit for AP or Force Weapon for dmg.
-CM: gotta keep that DS up
-Astral Presence: for the 2 AP per sec
-Temporal Flux the slow is very useful.
How to Play:
Step 1: DS up
Step 1.5 (Optional): you can pop tele right off the bat for clones if ur not worried about needing a panic button
Step 2: Throw Twister's stratigicly for most slow and CM proc
Step 3: IMA FIRIN MA LAZARRR
When things get hairy use dat panic button to get out
Anyways, I don't think this build is really better than anything out there, but it's very versatile and it's fun to play. Also, Disintegrate is an awesome skill, and I'm really glad they finally made it usable
