EA isn't going to reach out to you. We've been asking for this stuff for years. Franchise Mode doesn't make them any extra money, so they don't show it a lot of love.
Also, what you are asking for is something people suggested in 2018, when they dropped the Vegas Franchise. I call it Coaching mode, so I can make the call on the ice while the game sims.
Let's face it, most of us like controlling the team, more then setting hot dog prices. They also need to let us hire coaches BEFORE we pick teams, so we can pick the best people.
Player's need to be fluid. If I put you on Line 3, and you stay there for a year, and the coach teaches Overload, but you are Behind the Net, you should change to meet line criteria.
They need to stop the TWF issue. They made a little headway with X Factors, but its still hard to get a +5 line chem with TWFs.
They need to balance the line preferences. No player you ever scout will have Hold the Line in defense and few (if any will have carry). 90% of prospect Defenders will be Pitch/Cycle.
When scouting a player, you shoulder get: Fits Top 4 D pairs, and all PK lines. It should literally give you a bio on the player's line preferences.
Chemistry should develop over time, based on similar line preferences and effectiveness of the line. Getting a +5 by adding a SNP, PLY, and PWF to a line with 11 green checks, shouldn't get you a +5 if those players never played together.
EA needs to make 2 different games. NhL RPG, with owner, coach, and pro modes, while making and NHL Online product for those interested in spending more money. LoL
