The biggest issue with GC in val is that there are no real ways to directly compare them with T2. No big events where teams from those 2 leagues compete, and thats why most players get stuck in a spot where even if theyre good in GC, they wont get picked up because they aren't "T2 Proven" and because of how shit T2/T1 financially is, orgs dont want to take risks and would much rather play safe, which makes it harder for these players to get picked up.
