Explosion radius
To my knowledge, all explosives now have the correct radius EXCEPT for evasive powder keg and refinement bomb kit bomb. Those two are only bugged when forceful explosions is selected. Everything else (even the reserve mines) should now have the correct radius.
I don’t think cone attacks have been changed at all.
I also wonder if there is any plan to change the timer on the Big Ol’ Bomb considering it usually is avoided. But again the timers on many things on the Engi don’t make much sense.
I actually like the long timer on BoB for PvP. It puts people off balance for ~2 seconds, giving you enough time to punish them with a net shot or immobilize bomb so they can’t dodge, or making them withdraw. It also lets you set up ridiculously long combos.
It has disadvantages, of course, like not being able to stop a quickness stomp and being really easy to avoid. But in general I find it fun to have to plan 3 seconds ahead, and it’s terrific when everything comes together. It fits the defensive nature of the bomb kit—it’s not going to hurt anyone who’s not playing actively attacking you, but it can severely punish those cheese builds who think they’re just gonna jump in and make short work of you.
