Ok like to throw this brainstorming in.
Underwater feels a little numb atm
And people ask for new skills
Why not give us qol utilities underwater like a hyper speed swim.
Or the skill to jump extremely high out of the water like a dolphin
Invisible skills underwater
Hold ur breath aoe attack which suck out the air of the water around u daze mobs in a 300 radius
Freeze the ice which immobilize foes in a 300 radius
Just out of my head but most happy I would be about be extremely fast underwater
