My CoH experience is very limited, but many crowd control effects could be roughly modeled as abilities with multi-target Hinder effects.
DoTs are harder. I can think of an ability or two that might deal damage to a target on their next turn if they roll doubles, but that’s not really a proper DoT. The basic concept of “do more damage but it taking time to happen” doesn’t mesh very well with the scene tracker concept, although you could probably playtest something that could sort of work. Action scenes in the SCRPG are on a tighter “clock” than most MMORPG battles are - and many traditional TTRPGs, for that matter. Dealing slow but steady damage without burning actions isn’t quite as good here.
