I think the following are widely considered issues players encounter.
1. Not enough credits.
2. Not enough ability mats
3. Purple gears drop rate
4. Not enough training bots
5. Not enough stuff to do
I know not everyone has he same problems but everyone seems to have at least one or more at some point.
The answer to all of these would be to expand challenges to work like they do on Sunday.
Perhaps reduce gear by 2 per day and credits and bits it's by 1 try per day.
This solves all of the stated problems and would be a nice gesture from EA.
They don't have to all be available at once. Say two challenges every eight hours or something. This would further expand the number of times a player would need to access the app.
