The AssMM has Mono to help deal with mobs, so it's not entirely single target. The Explo Demo would have a rocket for boss situations where AOE is simply undoable because of team placement, just like how the AssMM has Mono for when there are a lot more targets than he can OSOK. Considering the upcoming Delta rework, pretty high. An Explo Demo (who is all about AOE damage) paired with a Deltamando (who is all about mob control) can be a fantastic duo. The Deltamando will just keep things in one place, making it convenient and easy for the Explo Demo (and anyone else) to mow them down.
