Here are my suggestions, let me know what y'all think...
Issue #1. Too many missed assignments.
Solution: Aside from "tuning to improve blocking logic" (easy fix there) they also need to being back the "Center Awareness" Force multiplier from back in 2018. The, what would happen was the awareness of the center impacted the entire unit (I.E. Center AWR rating would replace the that same rating for the lowest rated other lineman)
Side note: This should also apply to MLB for linebacker and Safeties for DBs as well, buy I digress....
Issue #2. Slide/Rollout plays darn near unusable.
The blocking logic here is COMPLETELY wrong. Lineman are blocking "straight up" resulting in QB facing almost immediate pressure from the edge rusher.
Solution: Lineman should actually MOVE THE POCKET.
Rollout pass pro = Stretch Zone Pass pro TOWARDS the QB roll.
Slide Pass pro = Stretch Zone Pass pro AWAY from the QB roll.
This blocking scheme is ran at all levels of the game from high school to the pros. Not sure why the devs haven't properly implemented this in the game. Again...an easy fix.
Issue #3. Blitzing too OP. Especially from the edge
The devs have done a good job improving the blitz logic. Rushers properly "tandem rush" like their real life counterparts. The problem is, the offense was never given a solid counter to these improvements.
Solution: Check and Release needs to be re-tooled. Right now, RBs and TEs on Check and Release assignments are currently assigned to a specific MAN. This instead needs to be changed to scan a specific AREA. (Right/Left/Middle respectively) Scan those areas and if and ONLY if no free rushers comes from that side...go into their routes.
Also, give the user the ability to ASSIGN which side to scan for Check and Release assignments in the middle for RBs.
Issue #4. Lineman not properly engaging defenders. Not ideal. Please fix.
For these reasons, it's not even practical to run base/heavy sets at all.
