Lag problems appeared for me VERY suddenly about 3 days ago. No changes in my PC, no driver updates, no nothing. About the same time, I've also discovered a minimum of 2 other issues. First, in playing in groups of human players, casting some spells that OUGHT to work just fine, I get an "Invalid Spell target" message. Finally, after trying to recast about 5 or 6 times, it finally accepts the spell command for some unknown reason. This began happening, also about 3 days ago. Second, quests that a group of humans play together, especially item-related missions, only one person in the group gets a mission success even though all fulfill its requirements. This happens more multiple missions. It forced the group to refight the mission up to 4 times, if 4 humans are playing the mission!!

None of these issues occurred with 2 human player missions in pre-Searing, or for that matter in post-Searing.
LAG is still the #1 issue, no doubt, however, but about 3 days ago, SOMETHING happened to this game! Arena.net, please look into your netcode situation! There's something seriously flawed that you had perfect during the first week of release! This is happening across multiple PC platforms with many different configurations, connection types, operating systems, and drivers. What's more, none of these problems were happening more than about 3 days ago! Question is: what did Arena.net do to its server farms, especially the Euro and International 'district' servers. Don't know about N. American ones, as I've been playing with friends in Europe.
Need confirmation of LIKE-problems from others on this forum. Thanks. Only want this game to succeed & lag like this will KILL it!
