I am really annoyed that I have managed to purchase a chest that even at the highest reward gives a unit that doesn't even add to my army. Simply trying to x out of it while it stuck in limbo lag land for a minute. Since 2 updates ago iPhone 4's lag like crazy now, I am very happy you had a 40 percent off sale, but pretty much already blew that on a lame chest I would never buy, I want to buy potions only (another good idea put in the game) but alas you cannot purchase the war potions unless mini boss or war is going on. I also like to mass purchase them with my gems when they go on sale for 16 and 20 respectively. I am almost afraid to touch my screen until the sales come up letting me buy the potions. I already upgraded one of 3 devices due to trials not being able to run on my ipod. Cant do the phone for 3 more months until my 2 years is up. Simply adding in options the ability to have to agree to purchase using gems (in a different spot on screen than the first step) or allowing the choice for potions only w/o switching it in options screen would be nice. I put in a ticket for the crate, hopefully get them back, makes a person feel sick for a moment watching that, and I know I am not the only one.
