Why don't you tell us why you like the floating thing?
Personal preference mostly, but I also think it makes sense.
- All the way back in some of the first Marvel games, Magneto was floating around. Why did he do that? Because he can! It is a display of power, to appear more intimidating and to show the opponent, that they have powers beyond human comprehension. The same reason why Ermac should float, because he can!
- Though it doesn't matter in a fighting game, as it would be OP, but story-wise it would give him the benefit of movement. He doesn't touch the ground, so anything that happens to the ground doesn't affect him. Again, gameplay wise it doesn't matter, but logically, it does. I see no reason for Ermac to walk around on the ground in a fight, when he obviously would get the upper hand in a battle for not doing so.
- And the personal preference; I simply think it looks cool! In X-Men: Next Dimension, characters like Storm and Phoenix were floating, again, because they can. Phoenix didn't float in Marvel vS Capcom 3 though, which I thought was plain silly - but she could jump up and fly around though. If a character has the ability to do it, I think he/she should, for the reasons I've stated here. I was hoping if Ermac returned he would do so, after having seen NRS doing so to some Injustice characters. And should Fujin and Sindel return, I hope they do as well.
It is fair enough that you and others don't like it. Again, it's a personal preference, and I will not judge you or anyone else for not liking it. I'm glad you guys took the time to tell me why though. ^^
