I’d like to start by saying that i thor enjoy the game and think it’s probably the best mobile MLB game out. I think there could be a few changes made to the matchmaking in both live matches as well as ranked battle. For example: my team is currently at an 89.1OVR, but there are times that my first set of ranked battle opponents include teams that are over 100 OVR. Same in live matches, I’ve already been matched against teams that were 105+OVR, and I was at a lower overall then, so I stood absolutely no chance. 
 

I also think that there is way too much of a gamble involved when it comes to upgrades and training boosts. Its a little off putting to have to waste hundreds, and perhaps even thousands  of upgrade material cards just to achieve maybe 2-3 increases. Especially with the drop  rates of the materials. 
 

Below are Screenshots of the latest round generated……..with less than 90ovr I don’t think I should be matched with any teams above 95ovr.
