Going to agree with the others about Scourge's solo/duo capability. If Devouring Darkness is an issue in zerg, keep 3 corruptions on main target while 1 or 2 on collateral targets. We're not saying that boon spam vs. corrupt is healthy to begin with, so maybe start giving support classes unique buffs like druid spirits, non-CC stability stack removal, aegis? If barrier sharing is an issue, make it weaker on non-caster. If F1-F5 are too loaded with debilitating conditions (looking at mesmer shatter here too), though condi clear haven't really been any issue in organised groups lately anyways, do at least give another burst attack on torch or utility. I mean, please do something to Serpent Siphon.
