I'm just guessing from my match play recently. When the black max meters came out, I played 80% them, 20% everything else combined. With the RZNs, it was 75% them, 15% black max, 10% everything else. Now I'm going up against 70% XI, 25% RZN/black max, 5% everything else.
Am I to assume that the XI is the "next big thing" these days?
