No, I think it is guild-verse wide. This proposal would be to change for all guilds. Not just t5. I just see the consequences in T5 the most cause I play there and mentor a t3-4 team.
I dont think anyone does. That would be the next poll/data to collect. I think a ton of ppl are getting steamrolled with the instant CA rotation. It would have been better to keep some training wheels on until the set has sold enough packs to assume the majority of ppl have access to the cards. Even then, those with modern cards are far and in between.
