I just feel that in our drive to make the tyrant viable, we are literary removing all that makes the dominator pretty unique to the IN. The tyrant batteries are fine, and the range increase is cool. Nova cannon is fine in a vacuum, but since the dominator exists, we need to keep in mind that the two become really similar. As it stands, with Sigoroth's revision the only difference is that the dominator costs 10 points less and is much more restricted...which doesn't sound too bad, but no other cruisers have identical loadouts at different prices in such a manner. Just food for thought...
The NC option seems really swingy, because a vanilla dominator is better than a tyrant with just NC, hands down.
We could make the dominator more common on our fleet lists, which would solve the problem right there. Nip it at the bud, I say.
