Health consumables can be very troublesome. In some RPG's you're not only trying to finger dance during combat to move, strike and switch weapons. You also have to try and trigger all those power-up and health potions.

I don't like button mashing the health potions more than the attack buttons. I hate the death by wrong button thing, you know when you miss the health hot-key and instead hit the one consumable that is totally pointless in your current fight. Then you smash the controller and blame it for the brain-finger misfire that was the real cause.

But much like has been pointed out it's not consumables that are issues. It's how the design integrates them. Overall I vote Hell-Yes on consumables.
