Don't know if this has been mentioned but here goes.
If the tactics part of the game stays the same there is one simple thing that would make things much easier.
I want both default position and individual player instructions.
What I mean is that when I create a tactic, I often tweak the instructions of a position depending on the player who is gonna be in my starting lineup.
But when I use another player for whatever reason in the same position, I have to change instructions to fit that player, which is annoying and time-consuming.
So if you could make individual instructions for each player, maybe even for each position the player can play in, then we could just choose via a dropbox menu what preset instructions you've saved to use when making a substitution or just starting with a different player.
