Hello mate,
Allow me to disagree on that, it is not the same really, by the same logic why not remove the DMC from the game also as well and move DC forward to "act" like DMC?
It just makes no sense at all.
And please do not get me wrong, I would not want DMC to get removed from the game, all I am saying is that they should add more positions in general rather than removing and make others "act" like the removed ones did.
And here I am not talking about adding some random fantasy positions, I am talking about positions that exist in the real world.
Another example would be the sweeper, people tend to say that you can move a bit down a DC with defending arrow and voila, he acts like a sweeper. Meh, I play formations with 3 DCs for like 5 years now, that theory is garbage.
To continue, another example is the attacking midfielders. Why do we have 3 (AML/AMC/AMR)? In my opinion, they should, of course remain in the game, but what happens when you move an AML or AMR in the ST's position? It changes the formation to a 3-attacking one. Again, wrong. Just add 2 more positions for wingers with the red icon, just like the ST's to indicate that you have 3 attackers in your team (this is how real football is by the way and the image I use in OP is from the wikipedia).
Lastly, allow me to present you with an example of the change that happened when they removed DML/DMR positions.
Let us say, I used a 3-2-3-2 (DC-DC-DC-DML-DMR-MC-MC-MC-ST-ST) formation, back in the days. This formation was considered as a 3-5-2 formation, which means higher ball possession (5 midfielders right?). When they "merged" the positions, it is now considered as 5-3-2, which means a defensive one. Why?
I can continue with many more, as I said this is just an example.
If it were for me, I would personally add the below positions in the game:
1. Sweeper
2. DML/DMR
3. LST (or some other name for left winger attacker in the same line as the ST)
4. RST (or some other name for right winger attacker in the same line as the ST)
Again, there is a difference between AML and LST or AMR and RST, hence the reason I added them.
1, 3 and 4 were never introduced in the game, this is just my point of view and in football world in general. Managers should be able to use all the positions available and not make them "act" like they should.
I hope I did not tire you, again, it is just my opinion and point of view.
