what if all guns other than m4 where removed from era.. and you could only use m4 ( with melees, bombs, etc)..what do you think era would be like? who do you think would be the top spar gangs, base gangs, Pk'ers, Sparrers etc?
the reason I say M4 is because its pretty much the most balanced gun in era hands down, with its damage, freeze, and it does teach you the fundamentals of spar/pk., because you actually have to know what your doing to use an M4 correctly.
just a thought, what do you think?
