Actually, I forgot to mention an odd behaviour or two of the tornadoes. Firstly, that in multiplayer you are completely unaffected by other players' tornadoes. That might be a balance thing, and I haven't tested it in PVP, but it's something I noticed. Makes it very easy for a partner to make you effectively untouchable to a lot of enemies, since you can stand there, but they get sent flying if they try to get close. Secondly, the tornado always tries to spawn on the ground if it can, but if it can't find ground close enough, it spawns at your cursor. So if you're high up and have wings, you can fly the length of the map. Again, not sure if this is intentional, though it does make finding floating islands a breeze (pardon the pun).
