The incompatibility tier kills this game for me. I have been subscribing to Royal Pass for how many seasons, and I've spent certain amount of money to buy UC, mind you probably up to thousands of dollars, but due to this new incompatibility tier rule, I can't even team up with my regular friends. Not everybody plays to get high rank. Not everybody target to get top tier. Some are willing to spend just for fun playing with friends. Seriously I regret paying and supporting this game.
