Am not quite sure about the biggest region seeing NA and like EU over all but i get what you're saying i do believe they will become a massive region in valorant and most likely dominate when their time comes
They definitely have one of the most passionate fans and I really love the Turkish teams , but you could find a lot of toxic and braindead fans. You cant do anything about it since there will some hundreds of dumb fans among millions of fans.
I agree, even though a few of them are extremely toxic I can understand how they feel when they are rooting for their country and I think cringe people hate it in minor regions, maximum respect for Turkish players, they are very good mechanically.
