Everyone with skill and an m4 hugs the bottom and spams (including myself) I've seen it, so don't deny it. That's just how people win spars these days. Balancing the guns would definitely change that. Any bottom huggers would easily be destroyed by a shotgun/m3/PBP if they weren't so slow/freezy. As for melee weapons, I haven't played PC era in a really long time, so I don't really remember much about how they were used in spar there, but on iEra I find it extremely easy to run+shoot+dodge anyone who's stupid enough to melee against me. I would love to see balaned guns, sparring would be mroe of a challenge that way. But the more balanced the guns get, the more "pro sparrers" there are...and that concerns me.
