My take on why we don't see our favorite teams/players outside of the 6 mo. VCT, please comment your thoughts on how I see this:
Riot has a two factor system that has discouraged places like ESL or other major tournament organizers from hosting Valorant. One, the obvious LoL debacles from the past, these huge tournaments are hesitant to work with Riot from these blunders. Two, if you read the 'Major Tournament Guidelines,' they only award these licenses to exceptional candidates, sounds like an application for a SEAL team. Given their reputation and these lofty requirements, it makes sense it doesn't exist much. Riot seem to want to both monetize, and have strict conduct regulation on casting/format/sponsors involved (they very much hesitate to have betting sponsors, for better or worse depending on how you view these things). What I think they are missing being this strict, is why yes, they don't get as much money directly from 3rd party major hosts, they miss out on general game exposure for half the year pretty much, you can decide for yourself what is better for Riot themselves.
I've heard Sideshow state on his streams that the team/crew does events for Val, does it for league also (I don't watch league so can't confirm). Wouldn't you think there is plenty of casting talent? Why do we need to bounce around LoL schedules for 3rd party tournaments? I think its partially because of Riots, in my opinion, overbearing nature on conduct. They want the same casters so that this conduct regulation is strictly adhered to via already trained talent. They're worried about a 3rd party event hosting going poorly enough that it reflects badly on their game it seems. I think this is a misread by them, if ESL had casters that said things controversial or that they didn't agree with, it would reflect poorly on ESL, not Valorant, but that is my opinion, and also Valve's take.
From the pro player/viewer perspective: I think we are getting the short end of the stick in all of this, imo. Point blank, I would like to see more high-end Valorant.. I know a lot care about both, but me personally, I don't care about LoL at all, its an entirely different game. Pro's, this has been stated by a vast amount of them, they want to play more, have chances at more money outside of VCT contracts. Individual team brand orgs also lose alot here (NRG, SEN, etc), would want their brand represented more often, and return more exposure for their investments.
With all this said, my TLDR take on this is that only Riot perceivably wins (debatable considering they lose lots of general game exposure), everyone else (Viewers/Players/Team Sponsors/Outside major tourny orgs) lose hard.
