Shotta here 
Tanker - id probs say Ice/SS/Fire-Ice or WP/SS/Fire-Ice, they both work good but if u face somethin with -regen then WP just falls lol. but perma hoarfrost with hiber ul do good, with the 2 phase rule (not sure if that works still) no point in phase :P
Blaster - Fire/Em/Cold hands down, dnt need to explain
Controller - agree with the rest, ice/rad/psy is the shiz lol, i remember spag on his, undefeated ..... lol, i remember defiant vs union fights, no1 decent from union went, but we all joked about spag goin in by himself and winning , was god like lol, but ill/ta can be really annoying too 1 on 1 lol
Scrapper - id have to say spines/regen for the mobility, although not big fan of spines damage, broadsword hurts alot more lol but not big on mobility, i know that from my bs/fire scrapper wot does 1.5k dmg with headsplitter lol. regen > fire, hp isnt enough on the heal for scrappers and their alot squisher, so regen always wins.
defenders - well spoilt for choice really, rad/psy/psy is good but so is rad/sonic/power lol, cold/psy-dark-ice-sonic, their is alot to chose from wen it comes to defenders. i only got the 1 but really like my cold/ice , i cant seperate which i thinks best lol
