I know people vary on what they would like in RTTS. I will be honest I have more fun playing in the minors in RTTS. I make it to majors i usually start over. But i will say i did like some things from old way like depending how well you did in the showcase determined what round you went in. Still not sure how i feel about archetypes, points being used where you wanted also to some degree was good but had annoying things as well.
I would personally like to see it take longer to get to majors. Seemed like when relationships just started to get good either get traded or sent up. I know that you get at bat, fielding, boosts to attributes from relationships but overall it's kinda pointless until you get to Majors.
