This applies mostly to hunt mobs in the overworld, but even TOP I think ran into this problem with a few cases.
This has been addressed numerous times, DoT doesn't necessarily need to occupy a debuff slot. Slipstream is a DoT effect on the ground, no debuff. Flamethrower is a channelled DoT, no debuff. A single debuff slot can have some nuance added to it by buffing it (whether it's before like bristle on BLU, or a hypothetical new effect that upgrades it while it's on the enemy), or by extending it (old Contagion). Even all that aside, their design doesn't reflect this debuff slot concern considering DoTs that do not take advantage of a DoT's properties exist (Sonic Break, Circle of Scorn), and Reaper has an exclusively personal debuff that exists with theoretically 100% uptime when it could just as easily behave like Storm's Eye or Gekko.
