The new tactical system is undoubtedly a step backwards from previous iterations. It appears that EA are happy to create a fairly rigid system, and then you need to unlock various cards/evolutions for it to even remotely function. No doubt they guess this will generate extra revenue (as unfortunately your intelligence can't give you the edge, only your cash bought cards).
However, there is an issue with this. The current version of the game is dull, utterly unrealistic and bug ridden. I was the last of my friends to stop playing Ultimate Team (in November), as it's a baleful experience. So the money we'd have spent, is lost revenue for EA. We do play Pro-Clubs from time to time, as a social thing, but it's pretty evident from the gameplay there, that the development of the game is devoid of any meaningful plan to deliver a football experience.
All in all, the new developments in player roles, and tactics with less modification, has been utterly regressive. They can't even make some of these roles work properly either, i.e. attacking wingbacks that don't attack for example.
