Be angry that my day off from work was today, I won't be off again until Sunday, and I never have any time to do anything except on my days off, and even when servers come back up, I have a meeting from 6-9 and then raid 9-12, then have to go to bed and go to work tomorrow. So, if servers come up by 2:00 or 3:00 EST, I'll have 4 or 3 hours to do LFR and dungeons and shit, then I won't be able to do any considerable amount of things aside from a few dailies and maybe one dungeon each day, excluding Saturday because I work literally all day, until Sunday, which is close to reset on Tuesday and no one is doing shit anymore.
So basically I complain on forums during maintenance.
lol, this seems like such a silly question to me. I guess I have too much stuff going on / work to do at any given time that it doesn't even cross my mind as a problem if the servers go down, aside from the inconvenience if I'm in the middle of something.
Or put another way: I always have something else to immediately switch my attention over to, since I always have more things I need to do than time to do it. :p
If I'm working, no big deal, I play when I get home. If it's my day off, still no big deal, I clean the house, do laundry, watch some tv, surf the web, read a book. Whatever needs to be done until the servers are back up.
