You know, I would appreciate a thread that detailed what recoveries the hitbox of eruption defeats-someone should do some research on sweetspot sizes, which character can sweetspot through eruption with their recovery, etc.
In the meantime, I've been tooling around with Ike in training mode.
Anybody remember that big to-do about Ike's eruption spiking? Guess what? It's not hitting with just the tip that does it, although it may deceptively seem like it. Ike's sword is a lingering hitbox after the burst of flame. It seems that a grounded eruption must tip to spike, whereas an aerial eruption takes advantage of that lingering hitbox on the way down, DRASTICALLY increasing the vertical range eruption has, therefore giving you much a much more forgiving period of time to spike, since the tip of the sword travels through more space.
Of course, this isn't going to effect much of anything, since you'd have to jump offstage or fullhop offstage to do it, but still...
On a side note, does it bother anybody else that the initial start-up of Ike's fsmash (holding it behind him) clips through lots of characters without hitting them if they are standing directly behind him, but not if they're jumping?
