Can someone give advise on what is the best balance to have on positions?, (I.e. 6 def, 8 Mid, 3 rewards, etc...), it may sound easy, but after knowing that on tactics we need to have different formation to beat Eire 'better' teams or "odd" formations, I realized that just having one extra player of each position sometimes is not enough because of injuries..., or maybe having only 2 MC may not be sufficient..., any comment?
