Right now one of the key issues is Min-Maxing. This is possible because you have factionwide forces. Thus the best of everything will be picked without any disadvantage. This facilitates the blob spam that enables a destroyer to "park off the coast... gg win". Ie Currently it is easy to have 3-4 heavy destroyers in a single deck. Coalition navies would do the following;
1) Immediately make it possible to limit destroyers to 2 at maximum more likely 1 destroyer 1 frigate as no nation has more than 2 deep sea vessels
This instantly helps with the blob spam as the real resilience in naval task forces are the big heavy destroyers.
2) One instantly can prevent combinations like Udaloy II and Type 037 escort through prototyping.
This stops the crazy tactic of protecting your Type 037 with an epic CIWS while also gaining the serious punch capability in the Type 037 that fires missiles in 2.
3) One can reduce factionwide availability to very low and use the availability mechanics of coalitions:
This helps the nations such as NSWP which would use lots of coastal craft. Having a large availability bonus for this nation is likely anyhow and thus their respective fast attack craft can be made available en mass. Coupled against lets say USSR/USA who will probably get a low availability bonus which will mean while having some powerful assets things can be controlled.
4) Above mechanics can be used to enable aircraft to be rebalanced.
Nations like NSWP would have good numbers of land based aircraft available which is not inauthentic with their doctrine and method of sea denial. Meanwhile USA for instance would have less available representing the fact they didn't have huge numbers of large land based airfields but instead carriers.
It is not just about prototype
it is about the availability mechanics. Furthermore this would much more easily enable the naval section to cost AP's and bring the potency of naval ability under control due to having to accept a trade off. Currently decks have 0AP and are faction wide. To quote Sarvik

To do this we must
bring Naval combat back into the normal deck mechanics. While national naval implementation would be ideal it would simply be too much work. Coalition would require a very modest amount of work. It would enable availability bonuses to be applied to ships which would enable countries like USSR to be overcome through "swarm tactics" which by the way was exactly how countries in the Eastern block, Scandinavian and Korean areas tended to work. Prototype would control the maximum number of destroyers per player to 1 with perhaps 1 frigate.
So again, as you seem to be focusing only on the prototype argument I shall list again:
1) Prototype controls number of destroyers available cutting them to between 1/2 and 1/3 of current level. That can only be a good thing
2) Availability mechanics allow nations with 1 destroyer instead of 2 to still function through a larger number of coastal forces than the coastal forces at the disposal of USA/USSR for example.
3) Availability and
prototype mechanics allow the control of air power to be rebalanced so they are potent assets. This enables the option for the naval battle to continue in some form once you have lost your sea assets to the opponent as you can still reach out and interact in a positive manner if your opponent is careless with his assets.
4) Coastal extension is my idea. I have suggested it from very early on. Combined with Coalition navies you would suddenly find MUCH increased authenticity, immersion, variety in tactics and better balance. This may not be as simple as a "hard limit" however it is a far better end result as it addresses more issues in a far more efficient manner.
