In the SFU there are command/leader variants of most cruisers, destroyers and even some frigates. These ships can control larger numbers of consorts than non-leader ships can in fleet actions, but mostly are useful for having a few more weapons and heavier shields than the 'line' versions.
With initiative being so important in ACTA, some care will be needed in introducing these ships to avoid an initiative 'arms race'.
As for the C8, perhaps it's a game design decision? The C8 is more maneuverable than the Fed DN, can outshoot it at long range and has massively heavier forward shielding. Arguably, the Fed ship needs something to make it competitive.
Although...the Romulans get *four* different classes of *cruiser* with a command bonus, and the KC9R *does* get Command +1, too...hmmm.
