Sorry but I cant agree its based on taste. Cooldowns are just the superior mechanic to use.
This is objectively not true. You are making a subjective statement.
Cooldowns would completely destroy D&D. You would literally need to completely overhaul every single class in the game. The reason why you don't start every battle by spamming your most powerful spells is because you have to decide whether it's worth it or not. A cooldown would completely change the strategy because there woud be no downside to using your most powerful spell any time it's ready. You can't just change spell slots to cooldowns and leave the rest of the design as-is.
I don't have a problem with cooldowns when designed properly, but Baldur's Gate is explicitly branded as a 5E D&D game and cooldowns are not compatible with that brand.
If you like cooldowns, then I have some good news. Larian already made the game you want. It's called Divinity: Original Sin.
