Region locked, with no notification or explanation. Can't play with friends. Upon many months of gameplay, saving up for my first real L+ shot, I spent over 35k rubies and 30 tickets just to get shafted by these horrible rates. The game won't be sustainable for very long if this type of system is in place. We've sped up from KR so much, that it's going to be impossible to keep up with the hero releases. Shame as I absolutely fell in love with the gameplay aspects.
