One fan's take: Game Changers is partly why Tier 1 has been slow to incorporate women and marginalized genders into team lineups. For clarity I am not saying GC is bad or the problem, it is a visibility issue and IMO it's not gonna just magically fix itself.
From a player perspective: If you can get guaranteed a salaried spot in GC (ie: Top GC players), is it always worth the risk to try to move up to Tier 1? For some yes and that is awesome, some would rather stay in GC for the guarantee of salary or for other personal reasons, also great no problem. The players/coaches should do whatever they think is best and I support them, just trying to say that sometimes moving up to Tier 1 is not what is best for some individuals, same could be said for collegiate players.
I think there is also a structural issue that is hard to overcome when GC and Tier 1- Tier 2 are entirely different seasons, no chance of playing against each other in official tournaments, and therefore less chance that casual fans see women and other marginalized genders play. I consider myself an avid fan of Valorant E-Sports, so I enjoy watching anyone who is good/entertaining play. A lot of viewers are not avid fans, they have a favorite player, team, region, or only watch International events.
There are a couple of ways to fix that issue, and maybe you can argue that nothing needs to be done. Flor is on a Tier 1 roster, maybe this could be the start of a huge influx of teams at least more regularly trialing and hopefully signing more GC players. Personally I think there is still a visibility issue and the most obvious way to solve it for me would be inviting the top 2-3 GC teams from GC Champs to Tier 1 Champs, or at the very least including those teams in a play-in or something like an LCQ with Tier 1 teams. This would mean larger audiences get to see GC players/teams play against clouted teams like SEN, 100T, etc.
