As someone whose main on live and on Homecoming is an Invuln/EM Tank, I'm going to throw my 2 cents in.
Please don't touch the animation for Total Focus. Yes it's long. No I don't care. The going up and then coming down to smash is so much fun!
Second. Please just return Energy Transfer's old animation to it. I don't care why it was nerfed. Blame whomever/whatever you want. Heck, blame ME if you want to. At this point I probably deserve it for something anyway. The self-damage should be removed, it will still lose in single-target damage to Psi-Melee, but if you feel the need to keep it fine, whatever.
Third. Please don't add in any special combos or "cute gimmicks." When I want that I play Street Justice. I play EM because I want fast, simple pomp-pomps of death interspersed with the slow up>>>down>>>bam of Total Focus. That's what the set was before the live-devs decided that EM had to die.
Fourth. Please give Stun the "Cobra Strike Makeover." Add some damage to it if it doesn't break the game.
Finally. Please port EM to Scrappers. It's never make sense that they don't have it. And, given all people's love of AoE, giving them a single-target monster set won't exactly be game-breaking.
