They need to make this game so that you can only duel against players in your own region just most other PvP games (with the exception of WC of course.) Tired of all these Japanese players on ranked/PvP event.
That’s probably what the op means by it being unfair. I agree, the same concept applies to other PvP games such as fort night for example. Some regions of players are going to be way better than others.
Meh, DL seems like a luck based game more than a skill based. The player who drew a better hand wins the duel, especially now with despacito dragon running around.
