In all honesty I don't see Combinators going away - they are a money-maker designed for the Whales. Those of us who are F2P or limit our investment in PT simply have to enjoy the game for no more than the baseball season because you get left behind starting by the All-Star break.
To me, I guess the price of the game is worth 6-7 months of fun with PT and the rest of the year I go back to the Classic game. It's just not worth wishing for a PT version that doesn't cater to those willing to increase profits.
Many here will defend the PT design because "time and effort" can compete with $$, but players like me are simply unwilling to make PT a major part of our life - especially when we don't have that many years left.
After a lifetime, I still love baseball, and the Classic game is the best available to "pretend" your in the career you wanted to spend your life in
