This thread is only 16+ pages because of all the trolling that followed an otherwise reasonable opening post. Apparently giving non-sarcastic answers is really, really hard for some of you.
Most of the responses that followed the original post are utter nonsense.
"Downtime is covered in the EULA/TOS." = a silly response. The question was not "should SE compensate us?", but whether or not there were plans announced to do so. Other developers issue credit for downtime despite having similar EULA/TOS. Not because they had to, but because they chose to. It's not odd to ask if this developer is planning to also choose to.
"It's scheduled downtime." = a silly response. How much scheduled downtime is too much? If they schedule 24 days of downtime instead of 24 hours, should we not ask about being compensated for that month simply because the downtime was scheduled? Half of you would be cancelling your sub for that month to avoid being billed, and the other half would be throwing a fit because you're stuck hip-deep in consumed time cards for the 720 day Cloud costume reward.
"It's $.40 trololol" = a silly response. What's the dollar figure where we're allowed to start asking questions? Is it written somewhere? Otherwise, get used to the fact that for each person it's going to be different. Some people obviously value their money more than others and/or are less willing to cut companies slack.
"Your compensation is the expansion." = a silly response. Did you get the expansion for free? I didn't. I think most of us paid for it. We didn't get it simply by agreeing to stay offline for 24 hours. The only thing access to the expansion is compensation for is your additional $40-$130 of payment plus your monthly subscription payments going forward.
Many of the people trolling in this thread will be amongst the loudest complaining should problems arise that cut into our Early Access period. And in the end I'm not sure what's more surprising.. the 16+ pages of nonsense that followed the original post, or how obvious it is that so many people can't think things through before submitting a response.
