Wind & water chest analysis

We haven't seen a good chest in Wartune since a long time, one which was good to open. Here is finally one, the wind & water chest. Most of the content is highly useful. This is not going to be a long analysis. I just recommend that you keep opening your chests at least until you find a mount. Here are the stats I got so far:

As you see, no luck with mount. But mount has 0,1% chance usually (I think all the free players on the server who got 30 chest found one :)) so it pumps up expected value to 20 balens. It's almost even worth buying for balens (with discount coupons and using the spender bonus packs too).
