That being said I would not mind if they did that for all ships to add a little variety. Especially with the multirole ships to allow them to be more specialized in a role.
There's no point at present. Combat is one-dimensional small-ship face-to-face. The entire combat model (and it's not the only thing) needs an overhaul to make more ships worthwhile. Also multirole is designed to not be perfect at any one task; the only exception is 'Anaconda' because it had to be (see above, re: combat model). It's not dubbed "the mighty anaconda" for giggles.
It's not the ships, or more of them, that is really needed at this point; it's a ground-up review of all ships, performance, combat and actual purpose. So that anything
new added actually has some sort of value proposition. Missions are in the process of slowly being nerfed into oblivion, the BGS has gone insane since cutter introduction (prices can change in as little as an hour or two) and there are very few reasons to have a specialised anything.
I have no idea what the Panther Clipper will be like. It's supposed to be genuinely huge (perhaps not even able to enter a station?) relatively impervious to small ship fire (queue screaming about balance if it
actually is; how will single brosif in a viper be able to beat it? oh the huge manatee!) and able to enact a form of planetary bombardment. The game currently cannot cope with this concept. At all. The ship will be compromised in combat if it's as agile as Cutter, will not bombard jack with the current weapons (class 4 hardpoint needs love; most of the existing weapon types are absent in this slot) and cannot operate as being relatively impervious to small ships, because the entire flight model is
built on small ships.
In short, a lot of stuff has been added but there is no actual reason to do anything, missions don't really embrace the plethora of new features added nor are the ships actually designed to operate in any form of combat above pistol duel at dawn. In fact almost all the newly added small ships have the same basic weapon slots. This isn't accidental. This is what "balance" demands have lead to. The same thing in a different skin, because differences are evil for reasons no-one can actually adequately explain.
So i'd far rather Frontier didn't add yet more ship models, until they get a better handle on how larger ships should operate, and invest some time in improving missions to actually utilise player wings, refresh powerplay to make it actually provide something of value; in short - refine what we have, rather than put more in that has very little replay value; it becomes endless grind.
The reason the recently added small ships are underwhelming, is that we expected there to be something new, but not actually
accepting anything new. The combat, mission, trading and exploration models basically mean that everything more or less needs to be the same basic formula. Otherwise you end up with a big, non-sensical deviation, or ships that are just entirely compromised for a function they are supposed to be able to do, because one person decided this should be the way a ship work for undefined reasons.
I really like this game. But there are portions of it that are genuinely crying out for some love and improvements. Improve what we have, so that adding more can leverage it.
