I didn't do the survey but I in large part am very happy with the game with no real complaints.
I have likes/dislikes, I don't think gameplay is nearly as bad as others complain about. I hit HR's fine now and didn't hit them as well when all the hitters had 85 power.
I used to like events/BR and don't see a point in playing neither. I'm not a fan of a super amazing chase card each week that is always a fan favorite. You don't NEED them for your team but man they hide a lot of cool cards in chase packs that you gotta sink a boatload of stubs into.
DQ I think is a good idea but I'm not playing for 45 mins, winning all my games and then running the risk of getting nothing. I'm just not going to do it, I'd rather run the draft conquest repeatable map and at least guarantee myself 15k stub minimum.
Collections are a bit frequent but doesn't bother me too much. I had beltran pretty early, I've got Ted/Raleigh but haven't intentionally gone after bautista or posada too hard. I also got seager early when he was a collection because he's one of my favorite swings.
I also typically play only on Saturday and Monday and am able to keep up with all the content pretty good...so I don't get bored. This is the first year I've played more offline than online.
So yeah, there are some dislikes but way more likes for me.
