could fix it with the fact that repels and bursts have less max items per ship, but possibly increase their effect in a certain way... the ammo is not a terrible idea its just the fact that the bounce of the bullets... you might wanna look into the fact that you need a lot more exp to get bouncing bullets while it is quiet easy to get regular once... sure it will change basing a lot, but at least there wont be as many btyers sitting there and spraying till their heart's content... and you can make it so once the person has bought the bouncing bullets it also slows down recharge/movement/anything else it can do in the negative... there are countless number of prizes you can give people... once excellent way is to lower the bullet alive time that way the bullet lines aren't too long or no bounce on a lot of the gun you get at lower levels, but remove the ammo system altogether. i think it will leave the spam that people enjoy so much but it will have a smaller effect on the attackers that way especially the ships, im not saying the ship sets are bad, im saying they can all be slightly different in role for example weasel can have 2 bursts and only 1 repel while some other ship can have the opposite, so all ships have a slightly different role
