I have not played since the patch but what I have heard has concerned me quite a lot. Making batting harder, thereby making Showdown harder and reduced XP across the board would be a kick in the cajones.
Conquest - I like conquest. I like the multiple maps in conquest. My only request for conquest would be to refresh the Main Map throughout the year. Maybe make it stages like in the evolution missions. You have finished the map the first time and earned Mays now do stage 2 for a new legend in a few months.
Showdown - I failed the 1st inning showdown on the first boss. I should not have and some bad play along with a pinpoint accuracy throw from center field to cut down the winning run at the plate meant I lost stubs on that run. Not fun. I will try again.
Moments - So far at least it seems that they are hiding most of the moments in Player Programs or Showdown. If you have issues beating showdown then you will be at a major disadvantage for the inning program. Plus for the Granderson mission, the doubled, tripled and even quadrupled their multi game missions which I am not sure anybody enjoys due to the need to back out to the menu between every game and no easy way to restart a mission.
Prestige Diamonds - I hate that the inning bosses which hopefully can be won completely offline are Prestige cards. If you are going to make cards that can only be prestiged in online play then make the Ranked Seasons or Event rewards be those cards.
Team Affinity - No major positive or negative from me yet.
My biggest concern is the ability to get to 300 points as an offline casual player. 70 from showdown, 30 from conquest (plus maybe another 10 if you average 1 star per stronghold), 20 from The Granderson mission. That gets us around the halfway point with some miscellaneous points for playing. Assuming they release 2 or 3 more player programs like Granderson you will still be 80 or 100 points shy of 300.
How can you make up that difference? Collections which will cost you stubs. The Special Edition Diamonds gets you a fair amount but will cost upwards of 50,000 stubs to buy the extra 5 that you need. The Prospect collection is going to cost much more than that for a whole lot fewer points. The other option is just to play a whole lot of meaningless games vs the CPU.
