Maybe its a good idea to play 5 kills in each map? TBH i think thats the fairest thing that can be done. 5 games in pure dps. and 5 games in hit and run. It should make players think outside the box and change their tactics. So lets assume a weak player does Poll hugg in first map, and lets even assume he somehow manages to get a maximum of 5 kills. In a straight fight Dps he will most likely lose. So to me the only difference that will seperate the two is who makes the mistake first.

The pole hugger or the DPSer.

Silent i would on behalf of the defence ask that 5 games be played in each arena. It is the fairest everyone can hope for. ( Unless both players agree to play in the same map)
