You just gotta lov'em :)

Dakiras: There are a number of factors that you have to take into account with regards to experience gains, some of which mean you don't actually have to deal damage. For instance, spotting an enemy, base capture (not applicable in this case, I know,) win bonus which is 1.5x, and also the first win of the day.
I can understand what you're saying, but other factors are at play besides just the damage dealt.
