i think that the osiris and the LN dread are to plain...i like the outcast battleship look, and maybe the blood dragon. i dont fly battleships because they are just 700+mill of cannon fodder in my eyes. i fly bombers and VHF
there are many meaning of "impressive" when it comes to that...
one is size : zoner juggernaut
intimidation : rheinland battleship
or beauty : ( subjective ) - liberty dreadnought
when you think of what ship causes the most "awwe" when it approaches - what ship makes the opponent wet his pants. - i think it is the rheinland battleship. ( even if its not really justified )
