This was a "Champion" Capsule. Didn't people say that you get a champion of another region once you have all the champions in a region and open a Champion Capsule there? I'm very disappointed and confused now..

Currently, Champion Capsule of a region can only drop champions from that Region. If you have all champions from that region you will get shards instead.
That being said, we are looking at this right now to determine if this is the right reroll logic. We are potentially changing this within the next 2-3 patches.
