Have you considered the option that weaponskills simply wont cost anything and that MP usage would largely stay the same for things like Foe Requiem, Holy Spirit windows and so on? It would break current PLD if weaponskills would cost MP and I dont think there is a smart option for a physical-magical hybrid going 5.0.

RDM weapon (unenchanted) are generally awful compared to even Jolt I + Verspell enders. Even Moulinet would be a waste with 80 potency when Scatter has 110. So TP cost never really limited weaponskills on RDM; balance gauge did.

PLD TP costs on any of the comboskills does jack, it only limits Total Eclipse in long aoe pulls and Shield Lob + bash. Lob would simply be cost-free, bash be made ogcd. Total Eclipse is kinda meh and apart from subpar dungeonpulls it isnt worth the hassle to put it on MP to limit it only to rework the mp economy around riot blade and sheltron.

All that aside I think getting rid of costs on weaponskills gets rid of punishment for skillspeed builds or generally fast gcd jobs like samurai and monk, which is good imo.
