Melee only isn't bad. I do it all the time.
Granted if I'm in the zone, I can Punchan Heavy my way halfway up the scoreboard.
Half the time when I'm not in the zone, I just end up becoming a Distraction Heavy.
People like to focus on easy targets, and forget there are people with guns behind them
I do sometimes whine about people having no honor in facing Punchan Heavy, but thats only to hopefully start a wave of punchans. Nothing too serious, as if I was serious, why a I Punchan Heavy?
And when they do usually settle for melee, half the time it's a pyro with an axtinguisher.
