Just want to say that T5 is a very good fight...
One of the main problems with it is that none of the preceding fights actually prepare you for it.
It's also quite unforgiving (get knocked into wall or hit a twister and you're dead)

Two things that would help the people still struggling with it would be 1) no massive damage (essentially instant death) from hitting the wall, and 2) change twisters so they just blow you and others up the air with minor damage instead of certain death.
