Tonight, around 3:30am EST, Ost Dunhoth Wound Wing froze up on all 12 people in our T2 kin raid. Also, earlier in the night, around 2:00am, we tried T2 Flight to the Lonely Mountain. Again, all 12 people froze up at the same wave [4 summoners]. This experience in Flight T2 has happened multiple times for the past month or so now. After the server reset on Labor Day, we tried Flight T2 and it seemed to be alright, which is why we tried it again tonight. In my opinion, it ridiculous that playing around these kinds of lag issues has to be in a users skill set. It is also ridiculous that you can claim it is a non-server side issue when all 12 players lag at the same spots, multiple times in a row, on multiple different occasions, with varying levels of processing power. Something has to change.
