I've been doing some experimenting lately. I recently built two teams of the exact same players.
One team is all IF players and the other is NIF.
They look like this.
GK: SIF Ruffier
RB: IF Aureir
CB: IF Nkoulou
CB: IF Thiago Silva
LB: SIF Kurzawa
CM: IF Verratti
CM: IF Matuidi
CM: IF Valbuena
LW: IF El Shaarawy
RW: SIF Di Maria
ST: MOTM Ibrahimovic
The other team is exactly the same except NIF. (All games played in singles matches.)
I played 20 games with both teams.
My record with the IF team: 6-4-10
Record with the NIF version: 14-2-4
In every game with the IF team they felt slow to respond, made bad touches nearly every time, made inaccurate passes and missed several clear chances. (All around felt like a very clunky, slow team.)
In every game with the NIF team they felt crisp, fast to react, and all-around fluid.
I'm still playing around with this but in almost ever game I play with the NIF team, they perform significantly better than the IF versions. I've been alternating these teams for the last week to see if anything changes but so far, the IF team remains clunky, slow and an struggle to win games.
Anyone else noticed this? Is there a reason they feel so terrible that I'm missing?
