Halo: Power Weapons or Team Play

With the newest addition in the Arena playlists, shotty snipers, I have a hard time believing people play Halo because it is team oriented. Out of the three options to choose from, I would have to say CTF would have to be the most team oriented game type. Next would be strongholds and then shotty snipers coming in last. This kinda bothers me because in a game where you have to win to rank up, why would you pick the gamemode that required the least amount of teamwork? People love Halo and say something like, “You really have to work with your team and the ranking system forces you to really do that.” Though with this recent addition, I don’t think I can believe that statement anymore because obviously the only thing people want, are the big guns.
