1)I want to learn fuuton, because of course, it's an awesome element, if you'll master it, you can perform many strong jutsus, there are some strong ninjutsus that only can be learned if you mastered fuuton... and it is the only element I didn't start.. what was a disadvantage for me, because I couldn't counter raiton very good... so if I also learn fuuton, I'll become stronger
2)Fuuton's weakness is Katon, because katon is fire release, and fuuton is wind release... wind contains oxygen, and fire needs oxygen to live.. so basically fire is feeding from wind, the reason why katon>fuuton
3)fuuton is strong against raiton, because wind is the natural insulatorr of lightning, so the lightning can't conjunct through the air
