So guys me and my freinds (xbox 360) were playing domination and decided to mix it up and use a class without stopping power

the weapons I use without stopping power are the tar 21 and the ump45, yes I do know that lmgs are good without stopping power, but I decided that I didnt want to use the obvious choice, and now im asking you guys what is the weapons you would use without stopping power and what perks you use ( not lightweight because that obvious ) so please give me some feedback because my freind could use it.
