Playing on Xbox NA for Haderus mainly. This is last crown jewel of campaigns for Xbox. I have heard talk before about all the champion point passives that could be the main source of the problem. I love the event and the effort on you're part and really hope this gives you a window of solution.
Honestly i do not think the cp made to much of a difference. playing over 10 hours the other day during the event it almost seems like its Worse? (Probably due to Double AP incentive, more people playing etc.)
I understand the que times too, more people means a longer wait. But when you get qued at 80 than half hour after you are in you get crashed out. (my NAT type is OPEN, 140mbps, direct connect, specs are good)
Tonight at Sejanus when all 3 alliances were going at it, the lag was to the point where its unplayable. Now if you are like me ( which i assume most avid pvpers are) than you get use to the lag and keep playing, even though its to the point where you need to double tap every ability press, constantly have your ranged attacks getting delayed, double tap your bar swaps ( which sometimes gives you 2 switches even though abilities always need 2 presses?). We all know the lag, and im sure we are used to it. But i'm sorry but the lag is awful, there needs to be a smaller cap pop put into place or better servers or tune down the FX.
Look i am not trying to write a story ( too late) and yes my solutions are worth less than dirt considering i have no idea the cost, effort or time for these problems i am typing about. But the lag is very bad, getting kicked out and re queing is bad. Dying than lagging out, re-logging in to have a corpse of your character unable to respawn unless you get lucky and a person revives you. That is bad. (get me unstuck does not work for this, Oh and thanks for the Hour cooldown on that).
I really hope the next 4 days give you some good stats, this pvp is great and i really hope you don't take advantage of your pvp player base by letting Cyrodiil slide and hoping they will keep sucking it up because they love the pvp so much. Because thats it in a nutshell at this point.
