making bosses better, how could it be done?

I still say RA was a great way to design bosses.

Sure chaos mode bosses...okay yea that part of them is pretty bad.

But the normal mode ones that are designed are pretty cool. Like how von bon's moves are lethal yet avoidable by timing.
Also pierie's hat tricks and transformations were awesome.
Queens switchs keep people on their toes [and unlike damage reflect THEY DO A NICE MESSAGE OF TELLING WHAT FORM IT IS]
Vellum is a peach and I hate him. >_>
