Excuse me what? And you don't know where I'm getting that from? How about you look at every time Minato has fought. Last time I checked Minato is not Kaguya or Momoshiki that can levitated 24/7 without touching the floor once.He doesn't need to keep his feet on the ground, no clue where you got that from.
Case in point. He cannot fly
What you said didn't make sense in the slightest bit.
He's never flew once when he fought Obito in fact his fought touched the ground several times this being one of them after he just used FTG:Like displayed when he fought obito he can use it to fly in the air so he can just juggle himself in the air endlessly and thus eventually catch him rock lee style.

And Rock Lee style? What kind of headcanon is that? Lee needs to push off the ground before he's able to kick. And Minato can't do any physical arts that Rock lee can do. He didn't get the training or the physical energy to do so. Even neji can't use Lee's moves this thing has been confirmed since Part 1 that only lead succeeded besides Gai. Kakashi and Sasuke had to copy it and train just to use part of it.
Yes he does. Minato has never FTG himself to any location that his knife/formula hasn't been. Nobody is nerfing Minato, you're seriously overrating his capabilities. This is Minato against Gaara in the desert, so of course Gaara has the advantage to win if everywhere is covered in sand. Even Tobirama is losing but anywhere else besides the desert Tobirama wins. Doesn't matter how strong Minato is the desert is the desert. Like seriously wtf I thought you were gonna say something logical not something like this.He doesn't need a firmly placed kunai to teleport himself to it either, everyone here i assume is purposely nerfing minato so gaara can win which he wouldn't even have a chance in all reality when faced against the yellow flash.
