There are lot of things I consider why I don't like to have bhlp.. Tidus' ultimate weapon damages more with a full hp and having 99999 hp will take lots of time to heal! besides penance damages you 99999 which means you have no escape. Also getting HP spheres from Iron Clad is such a pain.

I don't think auto-protect and defense 255 will help coz my overdrive will charge slower (at stoic) this is also the same with bhpl.

I'll post when I already beated penance with my current stats, but really I never had problems with dark aeons with my stats..
