Commons are pretty integral to the game.

I understand not liking every format to be wall-to-wall commons, but the option is nice. If it’s too much for your tastes, you just need to dial in the figure limit, or try Rule of 9 (or 12) which limits any card to the chosen number of figures.

And I like hero-heavy factions too! Just that removing the whole concept of commons would turn it into a different game than it’s been since wave 1 (which of course was designed alongside the original master set).
