Let's make this point by talking about something irrelevant-- Gloomhaven.
It's an RPG where you spend resources to upgrade your character with various stat buffs and special effects.
You want to get through shields, you buy the shield breakey thingy. You want to heal, you buy the healing thingy.
You can also spend a much more common resource, or less of whatever you're spending, etc, to get a random chance to do those things.
It's cheaper, a lot cheaper. But you it's not as good to heal or shield break at random times. It's good to do it when your opponent has a shield, or you need health.
Booners kind of have that same drawback.
Man, Gloomhaven is cool.
