U just can't jump to conclusions. We have never seen her ever use ftg. Minato could also have learned it frm someone else or maybe he made his own version of ftg. Kishi just might nt have thought of it. I only will believe in definite proofs nd nt assumptions.
Even if I cn consider that Tsunade cn use ftg(supposing), then I don't know what makes her the best ftg user. The fact that she never used it could mean she was nt so good at it. Also Minato is the.fastest ninja ever so definitely he is the best in ftg and we have seen so.
Also I agree that ftg doesn't need much chakra though it may vary from person to person according to their chakra control in that jutsu. Maybe Genma told Mei so bcuz it was a large distance teleportation whereas against Madara she would nt have required such a long teleportation.
As u say I went through the wiki. Body Pathway Derangement is presumed to be a lightning technique by what it looks like. But it's nt proved. I thnk it's a medical ninjutsu requiring low level lighting traces. So that's may nt be a very advanced raiton Tec. She has never otherwise used raiton techniques. That means she is not a high level raiton user. She is just a powerhouse of strength and a high lvl. medic ninja.
