Ill throw in my 2 cents; imo the core balance of disco should revolve around GBs, Cruisers, and BCs. Snubs and Battleships should exsist in more support oriented (and yes perhaps underpowered) positions.
For Battleships; it wouldve been awesome if they could be these overpowered lumbering machines of death. The catch being that only OFs can get them, and at max they get like 2. There would be special rules around them of course, but they would live up to their name.
This is impossible now, people dont want to give up their battleships. Still in theroy it would be great.
