pfft, I'm terrible, I know that, I only smash for 5k-ish, which I'm told is horribad, my reactions suck, &c. &c. &c.
I've no illusions that people can beat me w/o having to cheat.
But that doesn't mean I'm ok with seeing a bomb on the void door just disappear, even when I smashed directly on it moments before (ie, not possible to disarm it).
Hmm maybe he used resilience m8. Or another defensive cool-down that made your smash miss. It only takes 3 seconds to disarm the bomb.
