1st: It doesn't explode on contact. It takes TIME and was one of the most useless weapons in Megaman (used only against Megaman(?)/Negaman and GUTSMAN! *DUN NUUUUUUUUN!*)
That doesn't change anything. I know to stay away from bombs, but that's not exactly easy to do either.
2nd: It is strong but never to the point of OHKO. Unless you are showered with many people's bombs at the same time.
It did happen when there were a lot of bombs, but I KNOW I get OHKOed with ONE bomb. It has happened more than once.
3rd: What needs a nerf more? Crash Bomb or This?
I personally didn't find anything wrong with Crash Bomb, unless you meant the fact knockback can keep the players in place. Well, what can you do about knockback? >_> Hyper Bombs need a nerf more than Crash Bomb.
EDIT: This isn't a suggestion to the versions in general, but rather to the public. Could you guys please host more types of servers besides Roboenza and DM? Both have been overplayed to the point they're not fun anymore.
