A lot of themes about this.... Have the same problem, but feels much more good since yesterday fix

Happened to me and others from my group in Sanctum Ophidia yesterday. On first boss as an off tank and sometimes main tank, I couldn't see nor popcorns, nor the big aoe, nor the hole. I had to guess where the hole was to jump in and not wipe everyone. I had to guess when to move out of aoe on manticore either... when the main tank got pulled down. Even with this painfull lag, but wait... I had less than 150 latency and good FPS, except the occasionally fps bug, we managed to beat it on normal. Can someone explain? Particles max distance min numbers, all other settings on max. After the boss, most adds were spawning late for me, same with the poison, worst was that on the end boss the 2 llamia were also spawning late for me. Also two of us had a crash in the middle of the battle. Even experienced players have difficulties under these conditions! Imagine players who never done a trial or group dungeon before.

Enemies spawning with slight delay happened in group dungeons too but less often.

Crashes... crashes and crashes... no reports no nothing... the game goes to not responding and you have to ctrl alt del and force close it. Most of those crashes occuring on the bridge in VCOA where you have to pull through multiple adds and kill the mini bone boss to end up the infinite spawning of the mobs. Most of the times not one but several players from the group crashed at the exact same time ending in a full wipe.

Same here. It happens everywhere - dungeons, anchors, trials... I can aoe them and they deal dmg to me but I don't see them. It's really annoying, especially if you are tank and boss kills your DDs!
