I'll be cautiously optimistic for what they will do with it. For me no matter what they add or how flashy they make it look it, will come down to the substance that is added and if they finally take the time to fix the bugs/glitches that have been in Franchise mode going back to NHL 21, at least.
This a list of some of the ones I know of off the top of my head
-AI teams not being able to handle their own RFA's properly - by signing UFA's and then leaving the player on the team. This can be unrealistic and even cause good players who would get some sort of deal even if its only a one year deal to not play or force me to trade for them so they are not sitting out the year.
- To them not being able to handle the amount of contracts per team within the salary cap where as some teams could have as little as 24 out of 50 in NHL 24.
- To them using a forward on defense cause they don't have the same functions as a user controlled team to call up players or proper ones. Two instances here is having players in reserve and then slotting one of them in (forward), cause they don't have an extra defense men called up to using a 45 overall prospect goalie in an NHL regular season game (id guess cause they were med elite potential) instead of leaving them to grow in a lower level league and bringing up the actual backup (78-80 overall) potential goalie they had on the AHL team.
Honestly, the list can go on but I'll hope that they address this along with making meaningful changes to the mode (some of which has been missing from the game that existed in prior NHL titles by EA).
