I wouldnt consider it a bug as you dont score from it everytime like you did in the 10.3 patch and you don't get a ridiculous amount of goals from corners. I personally think its really unfair that the amount of goals AI scores from set pieces is ridiculous, and that you deserve some from set-pieces even it up a bit. By all means take out the corner set-up it takes nothing away from the open play of the tactic which is where basically all goals from. good luck. and btw use my V3 Rarely tactic, its better than this one
