Ignited Ground & Flying Enemies

Unsure if this is a bug or if this should be in the feedback section...

I'm trying to make an ignited ground build where I get one ignite then spread it with oil grenades.

Flying enemies (I think the ones I were seeing were called "wasp" or something?) are unaffected by both oiled ground and ignited ground. This is flavorful to an extent, sure, but feels really awful when trying to build around the ignited ground. To the point where for a while I was convinced the skill was just nonfunctional since the tiny mosquitoes with very little hp were taking no damage while I was testing out which support gems I wanted to use.

If it is intended, then consider this feedback that it would be nice if there was an exception for damaging ground. Let them avoid the slows and shocks, but at least let them be hurt still. If it's not intended, then thanks for looking into it.

Would like to up this as I was about to make a post about this interaction. From what I have seen wasp wont be damaged by ignited ground but bats can. Both flying units, just not sure which is intended lol.
