if what you say is true and users find the tactical uncertainty to be more annoying than fun then that would affect my viewpoint.
Truthfully, at the moment I find it's pretty much a case of "meh, anything could happen in this match" just before it starts.
It's still fun, but it could be more so.
Naturally, when I think about tactics "experience", I think about how formation experience works in Hattrick - and I don't find that perfect either.
Tactics could perhaps be held at certain levels by coaches? If you play those tactics you also get a bonus "maintenance" % (like practice levels on players).
If you make the coaches more important, where higher level coaches can maintain more tactics types at higher levels, this might make sense... (bah @ extra wages, but the advantages probably even out with this extra cost).
