I have a lot of flex wrapped up in my current dots, and I have the math all worked out for retirements and such based on the retirement refunds (I can even show you the spreadsheets)
However, if I needed to buy more flex, I wouldn't. I would retire a player instead.
A few months back, I tried to load GLB and it wouldn't load. I got the error message that said the URL didn't exist. I tried a couple times, it wouldn't load, and I said whelp, I guess they shut it down. I wasn't surprised there wasn't an announcement, and I wasn't surprised it didn't direct me to one of the other WGG games.
I just assumed (for that day) that WGG had shut it down with no notice whatsoever, because I guess deep down, part of me truly believes that's consistent with the way this company feels about its responsibility to its paying customers.
Later that day, I tried again, and the site loaded up just fine. Nothing was mentioned about a site outage earlier that day, and I went on about my GLB business.
So I'm unsurprised when WGG won't commit to its customers that they'll be able to use the flex after they buy it. And I won't be surprised when it suddenly goes dark. And that's why I won't be buying anymore flex.
