Brilliant post and I completely agree with everything you've said. I absolutely love RTTS and and main liner it every year. This year I was intrigued by the idea of a two way player especially playing in the NL. I decided to create a SS for my Yankees because Torres is not the future SS.
I really enjoyed playing every fifth day as a SP and then every other day playing as SS. Both loadouts were progressing really well and I was doing some damage at the plate even with equipment bonuses not working. I finally got called up to the bigs and even though I knew I couldn't DH the same day I was pitching I was already thinking long term about a switch to the NL.
Finally the day came where we were playing on the road at the Braves and I was starting pitcher. A light bulb went off in my head as I started at the loadout selection screen, I can only select one loadout so what happens to all of my insane hitting attributes in game. The answer was the end to the last remaining bit of immersion, my guy steps up to the plate and has 50 contact and 50 power base attributes as opposed to close to 100 in each for my hitter loadout. My SS is the best hitter in the league and here I am at the plate having suffered temporary amnesia and have forgotten how to hit.
1-3 at the plate on the day with my only hit being a grounder in the gap to get a single. Also had a perfect prefect die at the warning track, if it had of been my SS it would've gone a mile.
I don't know how this made it through testing, simple solution is being able to activate 2 loadouts for games - one hitter and one pitcher.
