Explodes Nearby Corpses rare modifier too fast

Just an observation i've had (and by far the mechanic that kills me the most). This is a very difficult one. You don't notice the rare has it until it's too late 90% of the time. Every time i've been shotgun stunned to death by it. If the rare has this, there is almost 0 indication that they do until you get chunked a massive % of your life then you're dead.

I dont know if slowing it down a bunch, or making the indicator alot better. Alot of enemies "bloat" then explode after death, usually flashing giving you a heads up what is coming. I don't know if something similar could be done at the very least.
