Additionally, depending on the scale creating large task forces can skew the scaling of the strength numbers that appear on the unit icons. Whilst this has no effect on the mechanics of the game, it can significantly reduce playability, because it reduces the player's ability to distinguish between the strength of his units at a glance.
That's easy to fix, exclude the navy units from average strength calculations and max displayed strength at 99.
That's the most egregious problem with task force sized units and what you are suggesting would fix most of it. There would still be a bit of a problem left in that players would not know the true strength of their task force units.
But there are other, less egregious, problems beyond that one:
1. As mentioned above, players would lose the fine control of their naval forces. As an example, if one were on the wrong end of the air superiority equation one might not want to risk an entire task force on a bombardment raid into enemy territory, but might be willing to risk a destroyer or two.
2. Scenarios would lose the chrome of individual ship names. By definition, chrome doesn't affect how the scenario plays. But that doesn't mean it isn't important. Otherwise, we wouldn't call those places Paris, London, Berlin, or Moscow. We would call them place1, place2, place3, place4, etc. Same for unit names. Chrome is a serious matter.
3. Reconstitution build time would be bypassed. If I evaporate a battleship unit (and that unit has an appropriate size) but it was not sunk, just sent to the "on hand" pool, it should take four weeks for it to reconstitute. But if that battleship was just an element of a TF unit, the TF unit is unlikely to evaporate. Since it will still be on the map, the battleship in the pool will be available for return to the TF unit the very next turn (which might be only 6 hours).
4. Reconstitution for individual ships could not be denied. For example, in my Okinawa scenario, capitol ship units are denied reconstitution. Even four weeks was too short of a repair time in my estimation. If only task force units were employed in that scenario only full task forces could be denied reconstitution. Not only would that be unreasonable, but evaporation of full task forces would be unlikely.
5. The "Unit Destroyed" trigger could not be used for the evaporation of individual ships. Again, in my Okinawa scenario evaporation of capitol ships trigger VP awards. That couldn't be done if they were just elements internal to TF units.
I employed "fleet-sized" naval units in my Soviet Union 1941 scenairo, but that was a corps/army scale scenario. In regiment or battalion-scale scenarios individual ships are the natural choice. Being forced to employ TF-sized units at those smaller scales would lessen the game.
