Upcoming Title Update (6 Aug) confirmed what the community already felt

All of this is desperately needed asap for this mode to approach 25. This and the ability to pick you uniforms should have do done by now. 

I'm glad you asked, allow me to list them off...

1. Saved and adjusted Depth Charts, carrying into Road to CFP games. Cause who the he**wants to spend the first 2 minutes of each game putting bench guys who are often MUCH better than the starters in the lineup? And that's ONLY if the person you're playing allows it. 
2. Weather and different kickoff times. Madden gets night games and weather in online H2H, why not college? 
3. Not having to run a 4-2-5 defense regardless of the team you have. 
4. More balanced Tiers, and not being forced to play vs a Tier 1 team even tho you searched for a Tier 3 team. 

I'm not sure what you want them to fix in Road to the CFB playoff mode but every improvement in the "Gameplay" section is an improvement to it, better blocking, better defense, among other things.
