After playing Grounded for a little while, I've come to wonder.. In a game that was specifically stated to not be a PVP game, but a cooperative survival game, there are an awful lot of ways to kill allies and a decent selection of builds get taken away with seemingly little reprieve. Mutation to reduce friendly damage and increase resistance to friendly damage is worthless because it takes a useful mutation slot and even still doesn't help with the sheer amount of damage that happens on builds, including debuff builds. Just wild to play a cooperative game and suffer more team killing than any Halo match I've ever played.
