I was worried about this at the beginning of the year, but since I don't do online anymore I've been curious how people felt about it until I saw this. After reading this it's pretty much as I expected. What I think they need to do to balance this is:
First, not put so many different buffs into one single ability (having 4 different things each get a huge buff is OP); Second, tone done the amount to which something gets buffed (a +7 in anything is ridiculously high).
I think the different tiers and the ability to master an ability is great, but if any stat within a player's rating is to receive a said buff, it would be far more balanced to have the buff increase by +1 for each tier (maybe up to +5 for a mastered ability). Also, it would be far more balanced to scrap abilities like "All-Madden Effort" that buff mulitple stats, and take a more focused approach on specific stats. "Bookend Busters" is a far more balanced ability compared to others that give mulitiple buffs, or large buff increases, or both. While this specific ability doesn't grant a plus to a specific stat, it does gradually increase how two very specific stats function making it a good example. It's focused, and doesn't do too much at once.
Also I think they need to remove buffs from playsheets and instead have each tier just unlock more available plays as a more balanced approach. I don't think they need to outright scrap everything, just refine what is most balanced and works best. What do you guys think?
