Most of the keepers agree that the current model for the Irra is ugly as hell, that's why we're asking for the replacement model in the first place, and that's why it's carried the name "super dildo" for the longest time.
Increasing range on the turrets isnt going to happen - if anything, the range is going to be reduced from what it currently is in 4.86. The reason for this is that nomads are getting nomad versions of capship heavy weapons, like pulse turrets, light mortars, razors, missiles, etc, they're also getting the same hardpoint splitting that other sirius ships are. In short, Nomads will be balanced with the exact same types of weapons that other sirius ships have.
The forward gun was suggested because it actually takes some skill to use, and most of us agree that there arent nearly enough ships with forward guns in the game right now. We also wanted something that resembled the Nomad suncrusher seen in the freelancer extended intro (though obviously we're never going to get something that big or powerful, so we went for a miniaturized version with the Irra).
The forward gun doesnt technically 'have' to be a real forward gun, it could just hold a heavy weapon hardpoint that the player can put a nomad light mortar or missile turret in. It doesnt matter to me either way if we get a real forward gun or not, I just thought it'd be an interesting change of pace. As I said before, the Irra is more than twice as long and three times thicker than a liberty siege cruiser, while only having 3 more turret hardpoints at the moment, so there's no reason it's other turrets would 'need' to be nerfed to make room for the forward gun, especially considering it has much less manuverability than those ships and thus would have a harder time using the forward gun in the first place.
