Did they literally say it was comparable to getting a mount? But let's say they did. As someone who has opened a decent number of chests in the past, everything has always been random. During the event when capes dropped out of chests, I got 2 95 speed capes and 1 90 speed cape in my first 100 chests. I got 0 mounts when I opened 650 more. During the event when those warthog dropped, I got an 85 speed in a bundle of 10 chests I bought. I happened to open close to a 1000 more and got 0 mounts. A guy on our server got 2 dragon eggs out of 10 chests. You have players that opened thousands and got 0 dragon eggs.They gave us other chest items to compare rarity to they said rarity would be same as that of getting a mount.Was going to say this, people don’t understand this, it works the same way with raid drops
Even if it had a 50% chance of an egg to drop doesn’t mean you'd get an egg even if you opened a million chests. High drop chance or low drop chance is still a chance at not getting what you had hoped for
The jackpot rarity isn’t the same as that of a mount...
So regardless of what you compare it to, it's all a chance with no guarantees.
