Hellhound flames do too much damage to zombies

I appreciate the intention of providing a new way to engage with enemies, but I think the pool of flame that hellhounds leave after being killed does waaaaay too much damage to zombies and oni. This is especially bothersome after round 31 when like 10-12 spawn each round.

Can we tone down the damage to like 30-50% of the current value? It’s doing like 75000 damage per zombie per second. I’d like a chance to mow the zombies down before they disintegrate. Same with Onis - those dudes fall apart after 2 seconds in the flame. I’m literally trying to race the flames so I can kill the enemies rather than just watching them melt.

Again, I appreciate the ability to use them tactically, like a little running Molotov, but I don’t think the current iteration is fun.
