I think that most people who end up being frustrated or intimidated by the FM series is because of the tactic creation aspect.
Sure you can get a tactic right for a team after a lot of trial and errors, but there should be better ways to figure out what is going on exactly.
What I am suggesting now and what I have suggested in the past is that there should be more explanations of what is going on.
For example, when you are making a tactic, it would be ideal to know what this tactic will be like. It would be nice if we could get a summary of what the 4-3-3 formation will do if we have such and such duties/roles. We do get descriptions of each type of player and role, but we get nothing when it comes to them playing in a group.
I want to know what would happen if I have a midfield of 3, composed of a Defensive Midfielder (Defend), an Advanced Playmaker (Support), and a Central Midfielder (Attack). How will they be working together in general? What will they be doing with one another when my team has possession or when we are trying to defend from a counter attack? How will they work with the defenders or the forward? Slider modifications should also change the description because a lot can change when you play around with the sliders.
It would also be really good to know how the tactic takes place from back to front as a whole unit. Tell us how the general plays and occasional plays will go about once we start off from kick-off or when our goalkeeper has the ball. What will our team look to do exactly when our opponent has the ball? What are our forward doing? Midfielders? Defenders?
How will our tactic affect our opponent exactly? What are the weaknesses in our tactic (according to our coaches who can tell us exactly what is what depening on their skill levels). Coaches (or maybe only assistant coaches) should also suggest specific tactics and tweaks if they are really good at the tactical knowledge skill (you must take into account attacking, defending, etc.).
I am sure that if we get a breakdown of how our tactics and tweaks are working for the team as a whole on the pitch, more people will have a less harder time playing. Perhaps more people won't turn down Football Manager when they get to this aspect, as it can be fun seeing how things are described different by just doing a little tweak here and there.
What do you people think about this idea? A reply saying "that would be too complicated" is not welcome in this thread, as this isn't a complicated concept.
