...it should make sense that you can provoke the same type of vulnerability cycle as Wintertouched / Lasting Frost.
E.g. "Firestarter / Deep burn". What would be even more fun was if "Deep burn" would confer, instead of extra damage, the inability to recover / regenerate any lost hit points UEONT. That would be far better than just a boring albeit powerful +5, and thematically aligned with fire damage too. Essentially it would mirror cold's needing extra damage because it has status effects, and add a status effect to the burn. Burninate!!
Preventing enemies healing is at least as worthwhile a goal to killing them faster as just straight up damage.
Agreed. If you want to do "flamecheese" without just adding a flat bonus to damage, I would suggest some amount of ongoing fire damage when you hit a fire-vulnerable monster with a fire attack with CA, or whatever the frostcheese condition is.Eh... it would be, if enemies ever actually healed. Very, very few do. The only ones that come to mind are the old MM1 orcs (who gained a tiny amount of HP if they hit with their encounter power) and monsters with regeneration.
And, I suppose, monsters with the Cleric template. But then the DM's just screwing with you.
