She needs to go co-ed or tier 2, you can’t stay in gamechangers your whole playing time and expect to get a shot at tier 1, it won’t happen, not for a single player.
Once she goes tier 2/co-ed with good players and dominate people will see and actually recognize her, she didn’t even even GC champs….. while it’s obviously a team difference on why she loses vs Tier 3 teams she needs to join one of them and actually lead a team at that level. not a gamechangers team that’s holding her back.
