I'm curious as to what the impacts might be in condensing these two skills down to one. My thinking behind making them one skill is that I'd like my players to be able to be flexible in certain situations where a heavy blaster of some description may not be appropriate. I understand that from a simulationist standpoint, it makes sense to have them in separate categories, but I'm concerned that placing my players in a situation where they can't tote around their huge guns would make them feel unfairly punished (especially when you consider that a vibro-ax wielding character could just switch to a vibroknife and not be any less skilled with it), or it might prompt them to shoot their way through the problem rather than deal with having a limitation placed on them.
And yes, arguments for, "It's no big deal and they can deal with it" are perfectly valid, but humor me, please.
I'm just curious if anyone thinks it would make a significant impact. I'm not the most experienced GM, so I'm concerned about making somewhat larger changes to the source material like this.
