We all clearly agree that the problem with Goldfish is, aside from tough repairs, its reliance on the main gun, that can be easily disabled for quite some time, because it's a large, heavy weapon, doesn't have an effective arc for a bifecta, and its side guns alone can't do much.
The tricky part in making it viable is to either do something that will prevent the weapon from easy breaking, or something to make the Fish not as reliable on its main gun in the first place. Either way, the fact remains that some people (Daniel for example) find Goldfish a viable ship, so what should be done to maintain the balance between making it useful for everyone while not making it too overpowered in certain situations?
There's a few options and ideas already mentioned a few times:
1.Reduce repair time for heavy guns overall (which will probably cause imbalance for other heavy weapon reliant ships)
2.Provide Fish's Main gun with additional coverage (that may or may not work fine depending on the amount of weapon cover, if it comes down to considering the idea it needs to be tested before making a final judgment)
3.Give the Fish a full bifecta (basically one gun facing front, but this may end up being overpowered second pyramidion with disable hwacha, armor breaking gat and kill hwacha)
4.Give the Fish a semi-bifecta (similar to Squid's, but working only at certain, smaller arc, which seems like an idea for me, as Squid, with its light guns with wide rotation arcs can make full use of its maneuverability, while tight heavy weapon arc denies goldfish some movement, cause even if you go for a bifecta you have to more or less face your enemy up front for heavy gun to be in range, thus not enabling you to circle around him with constant crossfire from main-side guns)
5.Place another weapon on the Fish's side (in case of front gun disable a Fish can be left with an option to turn for its side guns, thus not being as reliant fully on the heavy weapon, not to mention with engie splits often being one guy on hull/side engines/starboard gun and the other being balloon/main engine/port gun the balloon engie could use weapon closer to the balloon, with gunner taking the front port gun, leaving starboard engie on the hull, which in theory seems like it could work)
6.Leave it as it is(with some people considering the Fish a useful ship as it is now, that's always an option, and it may end up with the ship simply being used differently)
