Furthermore, I think the game's learning curve can be much more friendly to new users. BB tries to oversimplify the game by creating a "short menu" and simplified tactics in the Set-Your-Lineup page. I think these are inefficient means of allowing the player to truly understand what's going on.
Ideally, all new users would read the game manual in its entirety. This is a bit much to ask new players though. Instead, I think a series of concise videos with voice, perhaps created by users, is a good way of introducing the main aspects of the game. I think there should be one 2-minute video with a brief overview of the whole game and then specific videos for each aspect. For example, let's say I'm a new manager, the very first few times that I click on "Roster", there should be a video on top (perhaps give some kind of award for playing the video too) that explains what I'm seeing and what different skills mean. When I click on Weekly Stats, the video will explain the importance of gameshape, and how you can track training minutes using this page.
As a former user currently in DV, you have no idea how many users I see who just plain don't know what they're doing and don't improve. I can't help but sympathize with them when almost all of them go inactive because their teams suck and I wouldn't want to be in a game where I was losing and didn't know how to get better.
Now, many of you have suggested a mentoring program. I think this is a great step but the problem is getting enough people to reach out to new users and having new users want that type of relationship. I think it's much easier to just have the game manual gradually unfold in front of them as they explore new features.
