Here's my proposition: if a weapon can't break a block or mineral in a full combo, make it damage blocks and minerals twice per hit.
This couldn't possibly negatively effect game-play, it makes a certain degree of sense (why should weapons that hit with supposedly legendary force be so ghastly at this?), and I for one am getting really tired of being forced to bring a fast side-arm simply because my Sudaruska and Callahan are just such rubbish at breaking minerals.
Actually minerals and blocks makes bombs cry louder than two hit combo weapons.
