Time for my obligatory “sees the merit in both sides” post.

Personally as someone who loves to fiddle with tactics. (Whole reason I ever bought FHM). I am firmly in the camp of seeing such units brought back provided any worries could be worked out.
I believe with the options available, different teams would, not could, would have different groups to run. Many teams may look at who wins year after year and try to emulate that style the way NHL teams do IRL but it doesn’t always work due to player makeup.

However, we have to look at the fact that a large amount of the league simply builds their players largely by what their GMs say is best. Meaning that the diversity of options is largely rendered mute.

Add to that the fact that, yes the top 5 or so teams tend to be the likely winners as they are usually deep teams with high average TPE.

As others have stated, the simplification process of our tactics has done the two big things we aimed at. Simplifying so that more GMs have an easier time of things, and allowing enough randomness through this simple system to open up the competition more.

As RED just stated, it’s not as random as STHS used to be. (Something I lothed about that system) where we are at right now is chugging along just fine and, as much as I’d like to the contrary, changing is not really all that necessary.
