I’m against for many of the reasons already stated above. I have somewhat changed opinion though so I might be for it just so that we could be relieved of these silly threads.
When I wanted to sit back and relax a bit in the BF4 server I frequented sometimes, that had a scout limit, I just put a scope on an LMG and then I could keep doing nothing just as good as any scout. (Actually it was a Rush server so as defender one often had quite a lot to do.)
