In a year or there about’s I agree it could be a good move. Right now the PC player base is too small and the balance between the two might not translate testing only them. (Ptb’s are to expensive on console from what I understand.)
At some point it might be a good idea, once they have a good solid understanding of the cross play differences. I understand why they didn’t go that route to start and why they might not in the future.
Good suggestion even if it doesn’t happen.
