Ya ToC shouldnt require much movement, except for final boss. However I have changed the tactic of moving my guys out of his Death and Decay. I leave them in it and instead focus on killing all of his adds. Boss should stick to tank, no problem, while you focus them down. That way there is no need to strafe when they start exploding. For the rogue poison put up a nature resist totem and make sure all guys are standing about 5 yards from each other so only one gets hit.

Oh and to answer your question I use the same keys as you do Q and E for strafing my team. Seems to work really well.
