Football logic and game's logic (basis to football) is that you must have (at least) one tall DC, with aerial skill, to confront C-K (of course & the height of the player, in the game is a cosmetic).
Also for DR & DL who are playing in the wings of defense and confront AML & AMR, who have talent or the sa of sudden striker/long sudden shot, DW seems more useful.
I don't if this work that way but the problem is that the comments aren't helping to have any conclusion.
A comment like "but {your DC} with his aerial ability sending the ball away" , or something like this should be working as an indicator that in this action, Aerial Domination sa was activated but it looks like random.
