Thank you for taking the time to articulate your thoughts.
I feel like there is something there unstated in regards to right of existence; where older cards have earned more rights. This was my sentiment when chalice was restricted. Cards that have been in the format for a long time without causing the world to end. Having a never-ending card pool is highly problematic. It certainly feels like as a format, vintage is evolving much more quickly than legacy; and this is a little weird. On one hand, I appreciate at least some of the new cards. On the other hand, the sheer number of vintage playable cards is driving a greater rate of change than in the past.
I still wish that answers to cards would come as quickly.
