Along mid november-ish IMC gives top 100ish players getting extra keys to share ? they did so in CBT1
They did top 1000 in the CBT1 but it seems unlikely this time since they allowed unlimited sign up so the only reason someone wouldn’t have a key if they wanted one is negligence.
With 100k+ keys already being sent out I am not sure they will be giving out more through the beta, but you never know…
