I've noticed after running fully built trollers and doms that they are most useful at mid to late levels and their usefulness quickly drops off by the endgame, and are completely useless for challenge content and most incarnate content. Crowd control skills are resisted by a lot of itrial or level shifted enemies unless you're actively stacking hold mags. They are completely useless on 4 star challenge content at which point you are a net drag on the team. I'm not asking for trollers and doms to get a damage buff or be a solo class but I am suggesting they get some kind of buff to their CC to keep them relevant and useful for endgame and challenge content.
