I only ever experience this kind of lag while Iron Banner is live. I've posted about this many times in the past and it happens every time. And if it's a matchmaking system issue, well then SBMM is certainly doing more for connection than CBMM, though it seems like the lag is affecting a lot of things in the game in general. Two different platforms for me and the same issue. The things l see are things like someone teleporting after they melee lunge, Nova Warp doing no damage to enemies at point-blank range, getting noticeably shot through a Titan Bubble once... Idk, this is a repeat issue and I've never seen anything done about it like no one else experiences it or something, which is weird because it's specific with this event. And just in general lately, I've been finding myself getting stuck in the loading screen for getting into the Tower and have had to change characters to get out of it multiple times. Those lobbies are either new lobbies where everyone gets set to join the same instance at the same time or bad lobbies with too many players and a variety of syncing circumstances.
