I mean, it can stay at 50 FP. But don't forget the 8 round cooldown already does the job on blocking them from being spammed, under that.

The bots should at least last longer than two rounds. It's technically what Raigen said. Not even Youkai use up this much FP at once, and do much, much more than what a bot do. And maybe be a little more durable themselves. I had one little idea to make this happen and not mess much with the FP costs so they can still stay on the theme you want.

Good Materials - +15% HP/FP boost, -10% damage taken (except Lightning and Water) per Rank.

It makes a mild sense to make them more durable against everything, they're machines. And in a balance-wise, they can't be deployed frequently due to the high FP cost and gigantic cooldown attached to their deployment skill, so that justifies why they should stay around for a little more than your normal Youkai.

So, if Medibot, Metalaegis and Turret get tweaked to become more useful, Engineer gets this neat Extendo Claw from Spo's post and Good Materials offer them a little more survivability, it will be all that Engineer will ever need in like, forever.
