HAHAHA, I pretty much only ever play support, so I lay down suppressive fire like a beast. A lot of that was back when one of the extended mag upgrades for the RPK was something like 200 rounds in a single mag change instead of a belt. I was laying down fire like a fiend with that.
Sadly that was patched and changed. But I still prefer the support class. Right now I use the G36MG. Not as hard hitting, but fun all the same.
