You have a mount in the store right now that I'd love to purchase with crowns but I can't it only takes crown gems.
In all of the years since you've put these boxes and crown gems in the store I've never once had ANY mount much less the mounts that are supposed to drop from the boxes during their release, not once EVER. I've also NEVER received enough currency from the items I did receive from these boxes to even be able to buy a mount, not even the current once for 1,600 crown gems.
One is more likely to be struck by lightning, struck by a meteor or crash in a plane than receive a mount from these boxes even when I did buy them I have purchased 4 x 15 in the past to see if it was worth it. I long for the day when American courts eliminate box gambling systems like these from every game in existence in the US because it's not worth my time or money.
What's worse is there's not even any crown gems in the Tome of Tamriel system to even shore up the numbers to make it possible to buy them. You're missing out on purchases because these boxes are a disappointing waste of time turning people off from purchasing them. Going back to a system in which direct trade for real money would be preferable to anything these gambling boxes produce especially today when money is so tight.
