Please read , before you disagree.
Friendly fire needs to go due to:
Betraying for power weapons , betraying for no reason , even some times a team mate may miss and shoot you instead.
so this is how i suggest it works:
Granades still do damage to your team ,other wise it would be a granade fest.
, also rocket launchers , granade launchers too do damage to your team other wise it would take no worries wich leads to no skills.
please 343i do this.
