Smaller cruisers do turn a lot better than their bigger bretheren. The Consitution class cruiser turns pretty well. The Galaxy, however, does not.
get a cruiser the size of my advanced escort & tell me how well it turns.
il give you a clue, that connie is half my ships size and giving both mk12 systems my ship will still dance around it.
all because i have a ship thats got a legal Working As Designed exploit that gives my ship not only dps dominance over other classes, but agility dominance too.
