@Omnibender, Tobirama was also hailed as an extremely fast Shinobi,, so it makes sense to compliment Minato on using a speed technique better than he himself could.

And BFT, while it is a Ninjutsu, is a technique that boosts your physical speed. It's not FTG which is just teleportation (as you're well aware). Since the technique allows the user to physically move that fast, it's a physical feat, no? Sure you can discount it if you wanna know what Minato can do with no Ninjutsu, but considering it's the world of Ninja and BFT has different applications than FTG, I'd think BFT counts as a physical feat.

Even if BFT is used erroneously sometimes when describing FTG, the instance they appeared on the battlefield was almost certainly not FTG. If it was FTG, Minato could have warped everyone to the battlefield at the same time. And Minato doesn't have the battlefield marked to begin with.
