EMEA has more players that DOMINATE international events
NA has more players who are SOLID at international events
the fact that TH and FUT got into franchising is kinda shitty imo. EMEA is very top-heavy it's not even going to be exciting watching the league. You already know the 3 teams that will qualify and then it's between KOI, Giants and Vitality. The rest of the pack needs massive roster changes.
Also if one of KOI/Giants/Vitality want to actually displace fnc/tl/navi from the top4 they will need to make at least one roster change.
