I've always wanted there to be a bigger, mechanical difference between these two.
Ideally, I've wanted slug throwers to run out of ammo quicker than blasters, but in order for that to be fair, I'd have to up their damage and I'm not going to do that.
Right now, I'm thinking of giving slugs +1 Pierce for 3 (or maybe even 2) Adv house rule, but I want to do something similar for blasters and I can't readily think of anything. Anyone have any ideas?
