I posted a similar thread in November, but it didn't get much notice.
It really would be great to see the tactical side of the game expanded. Currently, because it is virtually impossible to efficiently and effectively command a fleet, I only buy cheap frigates and destroyers for the AI to fly. Also, because of the very limited tactical side of the game, I don't even bother entering into battles that I can't clearly win. It makes the campaign rather boring, actually.
I'd prefer to see the entire RPG element of the game be an optional play mode, and a true tactical option be made available. Currently, it makes more sense to just put all points into your main ship to make it unkillable and have a bunch of cannon fodder for the rest of your fleet. But with the addition of officers (and having to level them up as well I would guess), the game is headed even more in the direction of an RPG.
The problem with having the core of the game built around an RPG is it turns the game into a grind. Tactical play involves skill and offers a far greater variety of game play than having eventual super ships that eviscerate everything on the field of battle.
