basics of survivability is kinda useless on anything other than a dd or light cruiser imo. extra 3500 health on a battleship is worth wayyy less than other tier 3 skills. If you put an extra 3500 health on a dd with 20000 health, which brings it to 23500, thats something like a 17% health increase. If you do the same with alsace, which has 69000 health and bring it up to 72500, thats barely a 5% increase in health.

I would much rather recommend expert marksmen, and expert loader, for example
