It does feel like the push strength is a bit inconsistent lately. I push, I backdash, yet I still get caught in the bursters explosion.
Run, and let it explode on a teammate.
After that say “woah man, sorry, I didn’t see or hear it. Freaking bugs!”.
And continue playing.
Repeat it, with different moments of silence or lies.
I had same feeling this week…
It happened 3 times.
I pushed it, but it fell near me, and exploded too close to me.
If you have some ulti that gives you thoughness you can use it, and let it explode on you.

Yeah, so, Bursters are borked. It’s not just me.
I don’t think this is a bug, but intended behavior: Something I’ve noticed is certain enemies hitting the afterburners occasionally. It’s most notable with mutant charge when they’re charging someone else. Part of the logic that determines enemy movement takes into account the speed of the target when it aggros, so someone in Desperado with full Vulture’s Mark stacks are going way faster than any of the other characters (outside perhaps Scriers w/ movespeed talent and DD psyker). While this doesn’t explain the explosion distance issue it might be a contributor to some of the poxburster issues.
