I dono, a may be one of the few but if maintenance needs to be done it needs to be done.
There will be a new influx of plaers as of 2nd dec this year when XI hits the xbox 360. The sort of maintenance they are doing just now, although inconvenient, is essential for them to take the new players i guess.
As for everyones errors logging in, right now at least thats due to everyone trying to log in, stupidly i logged to a mule and tried to go back accross and go the POL-error mystery tour. But if you have X amount of folk trying to access server z which is only set up to take y amount of folk at once you will always get troubles.
So yes there has been a great deal of maintenance this past week and a bit, more than usual yes. Yes we have seen alot of login troubles.
But I cant speak for the rest of you, however i have found teh upgrades to be beneficial, i used to dc alot and i mean alot esp in jeuno and such, now though i havent dcd since the maint/uprgade and when i have its been my ISP and not SE like normal.
