I play ranged cav (I know I should die in a fire etc. etc.) and If I shoot someone 3 times I usually get 3 pts. The other day for a test I stood outside a building where there was a fight happening and got 5 pts for doing nothing, I didnt even have line of sight on the enemy, so it wasnt like i was distracting them either.
The whole being in range bonus encourages ppl to zerg (some for of team work i suppose), but at the same time punishes classes which by their very nature should not bunch up.
