Rallying, in my opinion, takes away from the heart of competition. It is a cheese. Having everyone that hit a target instantly get up from downed when the target dies makes sense in PvE, but i don't think it belongs in PvP. Downed state, as controversial as it is, is a unique and fun mechanic and I think it has a spot in all game modes, albeit with better balance. But rallying really should not be in spvp, especially in deathmatch game modes. If a player dies in a death match, all players that tagged that player shouldn't instantly pop up from downed state. They should still be ressed by another player, or rise on their own, or just die.
