Ok, yeah, lets put on aiming lasers...cause umm, we need to reenforce our knowledge of where our cross hairs are aiming... Yeah, bad idea for lasers.
Reflex Scopes, not a bad idea, but in the same sence, it is a useless idea.
Lets say we put on a 2x or a 3x scope on the M4 or AK47 or the MP5. Your cross hair size wont increase, only your vision aspect. Your gun will still be as inaccurate, and if you ask me, it would be harder to actually do a head shot. but thats just me, most ranges in maps are usualy close to medium range, and a reflex scope would be useless because the range isnt high enough to actually use one.
Ok, firstly, you should have learnt by now that if anything is changed in the game of CS:S it's met by screaming and complaints from the community. Therefore, Valve tries too avoid doing it. Also, with the new buying system, I doubt they will be adding any new guns for a while... Also, all the guns ingame are based on real guns, and there's no P90 with a scope on it, so as a last resort, I have this too say about your thread:
