“Admiral Cadance has raised the Heart Crystal flag! All ships to Flank Speed! All ships to Flank Speed!”

Yes, World of Warships have something similar to that. They come in the form of signal flags and Captain skills. Both which give a boost to what ship you’re driving. So for what you’re describing, it best to replace the signal flags with a crystal. So this way, it would feel like they’re getting a boost from it.

When the Crystal Heart is active and there’s a Crystal Princess on the throne, it dramatically raises the morale of the Crystal Ponies, and the entire Crystal Empire essentially gets a huge stat boost, but when Sombra sealed the Crystal Heart away it wrecked the Crystal Ponies’ morale, and they were easy to conquer. The effect is a lot like a “unit morale” or “fleet morale” stat in a strategy/tactics game– where units with a high morale score are more likely to win a fight and units with a low morale score are more likely to lose– so I was wondering if World of Warships had some kind of morale-based game mechanic where ships with good crews or fleets with good commanders are more successful in battle, since that would make it easier to assemble a fleet that would play like the Crystal Empire. Sorry if I didn’t explain that clearly enough.

Ok little confuse of what you mean. I couldn’t make since of what you said, or maybe it just me and my brain.

THAT FLAG CLEARLY HAS ONLY TWO HUES.

Just my own version of the Crystal flag I made for Wows  
Does WoWs have any gameplay provision for the effects of ship/fleet morale? I could see a Crystal Empire fleet having a lot of potential for interesting mechanics based on how well the sailors/ships see their situation going, with them being nigh unstoppable when they have a strong commander and a conviction of victory, but easily routed if their brittle resolve can be broken by a clever counterattack.
