We need more player positions so that a player that is all-round wouldn't be wasted.
For example, if a player with full LA have the following statistics:
Marking 18
Tackling 18
Passing 18
Long Shots 18
Dribbling 18
Heading 18
Finishing 18
It will be hard for all of his potential to be used since putting him at any currently existant position would be a waste to his abilities.
But these kind of players do exist in the real world and ARE VERY SUCCESSFUL.
A Sweeper and Free Position Player choice would be nice.
Also, please add something like FR, FL! Since we already have something strange like DMR, DMLs we can also have them too.
And last but not least:
All the applications of suggestions (though currently almost none) can be fine, but
PLEASE FIX THE BUGS AND REMOVE CHEATERS PLEASE, ADMIN!
