Man, this has to be one of the lamest excuses I've ever seen. Megaman doesn't have enough moves?
Really? I guess it's kinda showing their laziness above all else, though. Zero and Tron are both copypasta in terms of moveset, minus the Level 3's. They did re-work Jill Valentine completely from MvC2, though, so...yeah.
TBPH, I have mixed feelings about the fan-made movesets. One one hand, they are a step up from Mega's MvC1 system, but they do seem a tad...excessive. His normals really don't need to be weapons, as he's perfectly capable of punching and kicking on his own, including in the air. I also don't think he needs
that many special moves; all he really needs is a selection of around 3 or so to swap between. MvC's version of this wasn't terrible, but you really didn't have time to summon Eddie
and pick up the weapon you wanted before a smart opponent could take advantage of that. TvC's was far better, as not only was the switch one swift motion that kept you safe, but the weapon use was also streamlined but still very useful. Really it'd have been nice for them to re-work classic MM's weapon system to the point where it's more accessible in combat, but unfortunately Capcom either didn't think about it hard enough or were just too lazy too.
