From there, SMN instead channels their Egi for access to more directly manifest magics and for means of more immediate (though often less efficient) release (see old Ruin III operating alongside Ruin I; Fester, Painflare) while SCH focuses instead on the imbued Aetherpool itself, thereby able to effectively boil enemies alive through those aetheric excesses and disturbances (Broil) they created. This doesn't get carried out very well in the gameplay, but that doesn't mean the setup isn't/wasn't there.
And no, the devs almost certainly don't think that that identity is covered by a single, uninteractive DoT. But they also probably don't think about identity, period, at this point.
