Gunslinger Build (Lv. 10-200)

And for what purpose do you kill Leviathan or Pap for? The points certainly aren't worth the time.

Well it certainly made it easier to have an effectively larger MP bar to use the first couple of times around, when it wasn't repetitive yet. With 4000 MP I get over 650 shots before I run out of MP - that's a lot of invincible spam. It's not like RF is that useful for the early stages, either - it'd save a couple milliseconds per stage at best.
