Best Special Ability for DC/DR/DMC

[ElPocho]

for a Dr,Dl I'll go with corner specialist,I have and old 31 yo DR with corner specialist ability he made 14 assists in 11 games.

For a Dc I know aerial defender supposed to defend well in corners and score for you in corner but that barely happen like 10 % of the cases,in the other hand a DC with defensive wall is the best you can get two of them as DCs will protect well your goal from most of free-kicks and long shots .

about dmc I'm not a big fan,I use blue arrow in my mc just un case when my opponent play with amc if your team is strong it will work just fine especially I'm playing defensively most of the times .

I don't think defensive walls work for long shots, only for FKs.
I have never seen the SA sign blinking with a blocked long shot, when this is done by a defender who owns this SA.

On the contrary I get it many times when FKs are blocked
