That's a pretty solid strategy. For the most part the higher the player value the higher I have them in my lineup. I stagger lefty-righty too as much as I can.
I'm bummed because I could've used an upgrade at 2B. I have regular 5Star Altuve who's fine as a regular player but almost entire rest of my team is Prime or PotW so 2B and Catcher are really my only weak links.
Yeah I'm active on game, spend money on gold, watch lots of videos, and stay positive (I do communicate to customer relations when there's glitches or I feel something is unjust.)
