Why would that be a concern? It sounds like something they should encourage. There is a martial arts maneuver that allows you to break weapons (including guns) so why would a 1 PP power not help you out with that? Personally I think it sounds like a decent way to render someone a non-threat. Then again, for the effort in destroying the gun with your bare hands, I guess you could have just done an S damage punch and knocked them out.
Its like the old Sunder Weapon methodology in D&D breaking loot is rarely a good idea. Further down that path
how happy will your Follow pcs be when suddenly all their weapons start getting broken.
As to Martial Arts, if you choose to follow then elven thing make sure you get the kicking maneuver, lets face it
kicking is the best thing to happen to unarmed combat sense punching, and having a +1 to Reach is I'm told by
my friends among the math geeks is infinitely better then having a reach of 0.
Its possible to get bio-ware that will let you punch for electrical damage and after having taken a look at elemental damage types I would have to agree with getting Acid. So Acid+Electrical will give you 1/2 impact with a chance of the target losing an action a certainty of them taking a die penalty, and will begin destroying whatever armor/barriers you were up against.
So if your prioritizing, I would recommend kicking, an elemental effect (both if you can do Bioware, and just acid if you cant, it sounds like you got a bunch of Critical strike, after that i think the smashing power could have it uses but Acid will take care of that almost as well as that power and its cheaper. After you have maxed out all you can look at things like distance strike, adept centering, living Foci etc. (All being fairly costly, and really only making the strong stronger.)
