Please remove or put a timer on "on death" exposions!

I dropped a bell on an elite in a map, hit it twice and immediately died. There was zero warning, telegraph or chance to get out. That is such a B.S. way to lose a map. It has nothing to do with skill or fun. I hate it but I'd understand if I had to immediately roll away from every elite kill, if it was on a timer, but an insta explosion... come on. Frankly, the mechanic adds nothing to the game anyhow so better yet, just remove it please.

Just happened again. Killed a rare in a 3 map. Immediately was spamming roll away, my character didn't and I died instantly. Is this intentional? Is this the devs idea of challenging or fun??
