Its not just you, almost every random crew fill i played with over the last day or two are complaining about it. Even those coming in full purple kits. Something stinks in this game right now. People taking full clips of damage from multiple people running around laughing on prox chat knifing everyone down while getting shot non stop. Ive run with randos in which one kept saying follow me I'll eat the damage they cant kill me... they ran through grenades shotguns everything and never died. A few days ago I played with a couple guys that would spawn in run exactly to where quiet enemy teams were away from the spawns and wipe them laughing and exfil once the lobby was dead. People are 1000% not playing fair right now. And im experiencing more toxic chat behavior than warzone lobbies. Ive had a lot of fun with this game even though it was a bit rough early on but the end of the season has been absolutely awful.
I will add i believe Bungie has a similar problem to warzone with cheaters... they say they will ban people but they are too afraid of losing what little playerbase they currently have so they are turning a blind eye and allowing it to happen.
