The Iron Duke (18) could not be killed within the normal 20mins of time in a single match. The ammo elevator do not spread fire downward like any other battleships. For the past few months, I’ve never seen an Iron Duke die of magazine explosion. The only way to kill an Iron Duke is to kill all its crews. Which is extremely difficult to do before the game ends.
I personally think a vehicle should be able to be killed in a reasonable time which is short than the span of the whole game.
I propose an increase of magazine explosion probability from a burning ammo elevator for Iron Duke’s damage model, or a rework of diving shells.
