Find or design a TB a game like Underrail without cooldowns and balance it so combat isn't shit. Once you do that, then your anti-cooldown stance will have a leg to stand on.
Not like underrail, but earlier Might & Magic games, Dark Sun, ToEE... And again, balance is overrated. What is the most balanced D&D edition? 4e. They scarified too much consistency of lore and mechanics for the sake of balance. And I din't said "UnderRail has cooldowns, so is bad", I said "UnderRail has cooldowns, and this is a thing which I din't liked", However, the quest design is perfect. The scenario design is perfect. The encounter design is perfect. The ammo system where you can "load a single bullet" is perfect.
I just wish that the game had more dangerous psionics instead of psionics on cooldowns and that the game had more "exotic" ammo, like dragon breath rounds for shotguns, slugs, slugs armor piercing, .50 bmg explosive, 50 bmg incendiary, etc.
