Okay so the disadvantages of the first jutsu is that you have to constantly spew out wind from your mouth. If you get interrupted the jutsu doesn't fully form. Also when you do the 2nd jutsu from 3 moves per turn, it will take a bit of time before you can do the 2nd. Get it?
(Fūton: Fūsui Ranha no Jutsu) -Wind Release: Wind Water Wild Wave Technique
So this is a two part jutsu, I mean you have to release a wave of water first then push that water to it's maximum efficiency and power with wind behind it.
( Futon: Uzu sentou ) - Wind Release: Vortex Punch
A combination of a taijutsu/wind attack. Punch the person in the gut and then release wind chakra to add extra damage and also send him flying backwards. Now while this techniqucally can be done else where, but the use of the torse is more ideal because you punch then release. So which means you punch mold chakra then release the wind from your fist. Kinda hard to do, say you are punching in the face, you would actually miss the wind technique
