I preface this by saying I enjoy halo. The skill/ weapon and map control is superior to other multiplayer games such as COD.
I loathe players that camp the sniper rifle or other power weapons. I am proud that I get quality kills. I focus on the forces that can dominate a map (guas,banshee, sniper, etc).
I believe quality players should focus on dominating all aspects of halo- vehicular, snipe, DMR, etc.
I have become frustrated lately as the few players i am matched with that have decent k/d ( above 1/1) seem to spend more time camping power weapons tha inflicting damage on a map. I wish there was a way to weight the effectiveness of a players game.
