I don't really have time to watch it (and also it isn't very fun to watch when I don't understand the casters), but I try to stay up to date on what's going on
Tbh most people don't care about Tier 2 at all, and the few that do only watch their own region. Like, I doubt many people outside Turkey watch turkey challengers for example, same thing with Italy, portugal, brazil, etc. The only Tier 2 league that gets a good amount of attention is the NA one
