My name's from my old main (Ice/Axe). 🙂
Mass levitate is worth it. I have the might of the tanker proc for the +res and it fires 9/10 due to how many targets you can hit. With enough recharge you can keep that buff up consistantly. Psi blade sweep's chance for disorient doesn't seem that high, so I do like to have a proc in that, too. The proc for knockdown from avalanche works well but get the superior version to increase the chance of it firing. I can't be certain but I wouldn't go with a proc lower than 3.5 ppm on psi blade sweep. I don't think it would work often enough to be worth it.
