I couldn't get on more than an hour. I went to the store and in the meanwhile got disconnected from the server, then 3 HOURS go by and I can't login. I hate this! It's like downtime is 18 hours for me.
It was horrible... I was about tearing my hair out. I went to the forum for my realm and chatted with people there, we bashed on our resident High Warlord, Nicolai... That guy's an ass to da max.
My login was very slow last night, but it worked on the first try. Took maybe 5 minutes until I saw the character list. I only stayed long enough to check my mail and do an Alliance- and Horde-side census on Uther. I don't know if others were having stability issues in-game.
