I logged in my rogue, all the BGs were down.
I logged in my 5-box team and started Crypts. Server restart.
Logged back in, did Crypts.
Logged in my rogue and did AV, the lag was so bad that it took about 15-20s for the server to register a command. I think there were 5 kills for the duration of the game. Both sides just zerged to the generals with a few capping bunkers/towers.
Joined WSG and it was better but we experienced numerous other glitches like people getting rez boxes right on their corpses as they die and don't get ported to the GY. I have a screenshot of an 11 vs 9 WSG.

Add to that the madly scrolling combat log and all the spam in the trade channel and I dust off my mental note about not playing on patch day. Opinion reserved until AV is actually playable.
