Right. The difference is just what the resting %resource is. MP enters combat full. All other gauges enter at 0. (As you mention just a bit later.) Spender-rebuilder vs. Builder-spender.

The problem with migrating those systems to MP is that it's the equivalent of replacing Sentinel, Nebula, Shadowskin, and Vengeance with Fortificatis Genericis or whatever named Role Action. It takes things that previously at least had a separate skin for that tiny bit of distinct flavor and merges them into one for no other reason that that one can.

Else, the moment you actually do something with MP to give some reason for moving those melee onto an MP system instead but leave it as just a gauge-equivalent (no varied max MP)... now you have the balancing concern of varied potency-value per %MP. Do you Mana-shift the SAM? The NIN? On one hand, that's kinda cool. On the other... there's very likely to be just one, not particularly even situational answer, because those gauges were never meant to cross over.

/just food for thought
