So lets break down what this requires:
- New animations and mo cap focusing solely on the step by step of each submission. Now the current animations already do this to a point but based on your descriptions, I think the animations would need to be more incremental to show the squeezing and the turning.
- New camera when subs are locked in. You would need to be able to observe the intricacies of each adjustment and a wide camera angle would not be able to pick that up as easily.
- This is the biggest one. I play Madden. When I play I dont use the hot routes or line adjustments when on offense. I just play. I know what hot routes are. I know why I would use line adjustments. I just dont ever use them because that level of realism isnt needed for a game that I just like to pick up and play. The good news is i can still be successful at the game without using those features.
Here you are asking for every player to study a tutorial and learn what you need to do to either advance or defend a submission and there are 28 different submissions in the game. If you dont learn them, you are at a serious disadvantage when it comes to winning in a fight. That goes for online or offline.
Now you may say "How about two control schemes? Simple submissions and the new system." That could work but my question for you is:
What system do you think the average player will choose? I think it would be simple submissions because its straight forward.
So if most use simple submissions, why would the dev team spend time and resources to develop a system that will be a challenge to learn and that most people wont use?
