I want to start off by saying that this is not one of those cringe transphobic/sexist threads that are getting deleted, so don't modcheck me.
I think that GC is a great way to bring more of an incentive to women and other marginalized genders in the gaming space to compete and come to VALORANT as an eSport. In this, it's excelled, as I believe that VALORANT is the only major eSports title to have major events specifically targeted at this demographic, so it is objectively a success for Riot for it to grow as big as it is.
With that said, I also think that it's created an unfortunate feedback loop that may actually damage the ability of some really good players to play in the main VCT events and find success at that level. It seems like all of the female players, regardless of their skill level, who want to compete go straight into GC. The only example of a female player on a highly competitive team was Scourge on Complexity as far as I can tell. The feedback loop I'm talking about is this: Female player tries to go pro --> Female pro joins a GC F/A team --> F/A team gets signed and stays in GC, preventing any of the best female talent from taking the next step up to participating in T1 --> New GC team can compete within GC but not in main VCT --> Players on GC teams get hate for not being as good as T1 teams --> Best GC players stay in GC because they can make a living doing what they love. I know meL specifically said she got an offer to trial with Pioneers and turned it down, and I can see why. Not only is developing a connection with your teammates hard, it takes a long time. There's no incentive other than the desire to compete at a higher level for players to go from T1 GC to T1 overall (although C9W was probably better than Pioneers at that time already). If anyone has an example of players who've made that jump, please let me know, because I'd love to be wrong. I know teams like C9W and G2 Gozen do play in the VCT Challengers qualifiers and they do better and better every year, but I think most people would agree that an already-T1 team with players like meL or florescent on it would perform better than they are right now.
TL;DR: I think some potentially T1 skill level female/marginalized players have gone to GC instead of T1/T2/T3 VCT teams, and there are a ton of incentives for them to do so. I wish that these teams could be "The best" and not "The best asterisk"
