Things that need to change

[Johnist]

= farming materials from enemies a breeze haha

HP <-> MP = Infinite Bard songs LOL!!
Quadraslice for auto-attacks + Barrage = BRD auto attack 7 arrows at once = Legolas reinvented

How about an MP<->TP one or TP<->GP?

EXP+, Gil+, Spiritbond+...

What about a self-repair Materia, where it repairs over time (1m = 1%)?
