Crossplay desync. About 3 years ago Microsoft upgraded their network & inturn it made everything gane coded before then, have desync between PSN & Xbox. It was addressed by Devs from cod & halo, they fixed it or released new games on new code, other games rewrote the netcode, bungie ignored it which I kinda understand as rewriting the whole game would take years. Both platforms see issues Vs the other, trust me on this, what you see we see too but with PSN players. It's actually far worse on Xbox because outside the US (US is pretty much 50/50 split) the split is around 85/15 in favour of PSN so every instance, lobby, tower, patrol zone, is almost always heavily PSN, so were you (if you're outside the us) see 1-2, maybe 3, Xbox players, we see 10-11 psn players nonstop. Also the way the coding works your own team desyncs too so your own team can be teleporting, blinking, invisible etc. It's the prime reason I all but stopped playing PvP, don't raid & leave heavy psn instances. I've learned to live with it i guess but the insufferable thing I can't get past is tower travel, if I fly to a pc tower I land in 20 secs, if it's PSN heavy I'm looking at 3-4 mins, if there's PSN fireteams there I can wait 10 mins so these days once I get to 1 min not landing I don't even look I just change character & re-queue & I 99% land in a brand new tower with like 2 players there in 15 seconds. I'm told the biggest issue causing this is that 50% of PSN players are on old gen, & this causes severe issues for everyone matching them, but I don't know how much it affects things.
