Thanks for being honest Roeksha, just acknowledging that you guys know that there's a serious issue and are trying to collect data on it helps a lot.
We were capped at 36 players the first night post-move and very close to that the second day, and I have guildies from many countries and all across the US. I myself am in southeastern Indiana, so pretty East Coast. My experience in PvE was a drop in ping, from 78-350 on average to 30-78 on average. My ping stayed the same throughout both sieges, but I experienced the heavy lag and rubberbanding on both nights.
This I believe, from our experience, isn't necessarily related to region, and here's why: one of my guildies from Oregon was lagged by about 6 minutes behind on the first night and played in real time the second night. A pair of my guildies, a married couple, who play side by side on the same network, had completely different experiences both nights. One night they were both lagged badly, and the next night the husband played in real time whereas the wife experienced heavy lag. One player who is in Guadalajara, Mexico, played in real time both nights, but his brother, who goes to school an hour or so away, lagged terribly both nights. One of my players in the Philippines lagged heavily the first night and played in real time the second night. One of my other players from the Phillippines lagged heavily both nights.
None of these people changed regions between games, and none changed their computers or internet connections either. Some of them were in the same room and watched the other player have completely different lag issues.
During all of the severe lag, no one reported higher-than-average ping, which leads me to believe that the issue is with the siege server only, as we seemed to be able to communicate via guild chat with no lag, whereas say chat kept up with where we were in the siege timeline.
My personal experience both nights was very similar: the first night I played normally for about 10 minutes and then suddenly I started to experience the lag in the following ways- I tried to buff myself and nothing happened, I tried to mount and nothing happened, I was able to run around freely, but towers did not load.
I thought I was standing at Knin when finally my buffs that I had clicked about 6 minutes ago suddenly cast, I saw the mount cast bar and then within a minute or two I rubberbanded back to the bridge and found myself dead. An enemy rogue had hit me. He was teabagging me in a friendly way, so I attempted a say chat and nothing happened. He ran off. I hit the res button and nothing happened.
About 5 minutes after hitting the res button, I saw my say chat appear, and shortly after I ressed on top of the castle. During all this, I could hear my guildies having mostly the same issues that I had. A few people were playing in real time, and we could see how far behind we were by checking with them. I ran back to Knin, which my real-time guildies said that we owned, and saw no tower. My map showed that it belonged to the enemy. Eventually, I saw it spawn, and watched a fight take place, and watched one of my real-time guildies at the tower. I could target the enemy players, but when I clicked my offensive or defensive spells, nothing happened. I was behind by at least 5 minutes. I could see my guildies and the enemy, but we were all in different timelines. I saw my real-time guildie die, but my screen announced him capping the tower. In reality, an enemy player was capping the tower. At some point I died, but I never saw the rogue that killed me.
Perhaps the funniest thing we saw that night was one guildie who announced in a panicked voice that our pfactory was being attacked. As we had lost all three of our pfactories within the first 10 unlagged minutes in a castle fearless zerg attack, and it was 50 minutes into siege at the time that Madie saw it happen, we all just laughed. He was seeing something happen 40 minutes behind.
Another strange visual glitch occurred the next night. The enemy had broken down our central gate and we had rebuilt it quickly. More than one person reported seeing one of the players we knew was experiencing the heavy lag (because this guy is usually nigh unkillable, and he was being spam-killed by our few unlagged people) walking right through the front gate like it wasn't even there. I am sure this occurred because for him, in his timeline, the gate really wasn't there.
In worldchat after siege both nights, we heard reports of similar experiences happening server wide. Some people in other guilds interpreted the lag as use of the multihack, although I tried explaining that the lag was not player-produced. Players are simply not playing in the same timeline, and the ones who are closest to real time have a huge advantage over the lagged ones, although occasionally a lagged one can make a kill on another lagged one if they are close together in the timeline. One of my mages got her highest kill count ever, simply because as she ran around lagged, she purged constantly, and the lagged and unlagged walked through it. She never saw the people she killed; I bet they didn't see her often either.
Someone suggested yesterday here in the forums that this issue might be being caused by the new server company's bandwidth restrictions. I don't know a thing about servers or bandwidth, but it sounded logical when they said it. The problem is definitely that most of the players are out-of-sync with each other, usually by several minutes. Why some have no lag and others have lag as long as 10 minutes (or in the case of poor Madie, a 40 minute flashback) can't be explained by something as straightforward as region. This problem has too many variables.
