You know what? I wholeheartedly agree with a lot of that.
But it was in large parts the charme of the gamemode that lots of different ships could and had to be played. If you can chose to only play the strongest ship type, because, yes it is unbalanced for a destroyer, then who will spawn the offmeta ships? 100s of ships wont be played anymore because anyone that has it can just spawn the best ships, Iowa or Sojuz, whenever.
The counter was that, killing a 5.0 destroyer gave basically 0 Spawn points in a 8.7 ship and it could just be respawned with 0 SP point cost attached. Now, its a problem that it still cost SL to do so if you got killed by a ship youre completely outmatched against, but still that was rather cheap. Respawning an iowa cost 46000 SL…
And one hit with a long lance torp and hes gone, and with him his 600 SP. But that causes further problems that i explained in my post above.
If you could spawn your emden 50 km away from all the battleships, but there would be missions and enemies, be it bots or players, if there would be things to do for the ship you want to play in that moment, and these enemies where in the range of power you can handle that would be a different thing. But the snail never even started bothering improving the spawn point system. (Not SP required TO spawn but avalailable spawns on the map). There were no spawn points/ areas where only destroyers, or only cruisers could spawn. It was always: everyone has to spawn at one spot, and that spot is the only quick action, medium or close range fighting area. Except for coastals. That still could and where played. And even those could and have been viable, imagine that.
I get that people prefer playing battleships. I prefer that as well. But to, because of that, to reduce the pool of ships that will be spawned to a handfull of ships just aint the move. If you would want to reduce the pool of ships only to the ones that are fair fighting each other then we have lobbies where: Sojuz can only fight sojuz. Iowas are in a iowa-only lobby (at least for RB). And yamatos and musashis maybe with SoDak. Then Bismarcks fight only vanguards, Roma Italia, Richelieu, Jean Bart and Clemenceau etc etc. It is not ENTIRELY possible to make every 1v1 ship battle completely fair and everyone can only spawn this one ship because he wants to play this ship in this session. But the lineup of that nation, even combined with planes can alleviate that. 25% maybe even more of the matches were won by who had the better and more air players, did you know that?
Now, maybe it is not important or necessary to start with destroyers and cruisers that low as free spawn options. I think it could be possible to have Battleships as starting options for the top bracket.
The starting point for ships that cost SP (lets say for the top Bracket) could be increased to 7.0. Or 7.3 Or 7.7. People can spawn battleships for free. Rather good ones as well, that, in a team effort and with distraction of destroyers with torps and cruisers with good maneuverability could still bring down one of the top tier Behemoths.
But not the absolute top notch monsters. You would still need SP to spawn the ones 1.7 BR levels above the free entry margin. And that would still make lesser ships more viable, since, when anyone decides “today is sojuz day” not even any 8.0 ship on its own will be viable facing, defending from or attacking that thing. And if he gets swarmed, bombed or some nameless hero manages to torp and sink him, he cant go straight back into it. He will need to gain sp again if he didnt manage to bully half the lobby. But thats still better than making sinking him completely pointless-because same as you, he can just respawn for free.
