I was playing a new single player campaign on OP the other day and started out in an F5(The Klingon's favorite starter ship).
Thinking about the mechanics of the F-Rack in SFC and SFB(where it came from), I think the F5 and all of the Klink ships with 1 F-Rack and getting a raw deal, although kind of insignificant.
In SFB the F-Racks were mounted in Klingon Shuttle Bays which caused the ships to be able to only fire 1 drone from every 2 racks. SFC's implementation of this calls for the racks to fire half as often as an A-Rack does. This is fine for those ships with 2 or more racks, but kind of screws up the 1 rack ships. They should be able to fire a drone every turn from their 1 rack, in other words they need to be changed to an A-Rack.
The other "Feature" of the F-Rack was a chain reaction explosion in the shuttle bays when one of them took damage. This isn't included in SFC.
Just me rambling again.
Poor little F5's don't you feel bad for them.
