I'm not too experienced on sea maps, but I struggled to find any cost effective answer to scallops. It felt like I was coming out even in fights against armies half my cost, and tried different units from the sea lab throughout the game.

Gg wp Kingstad, well fought.

The theory is that Siren outranges Scallop and can hit them underwater. This goes out the window with Lobster. Mistral and Envoy outrange Scallop significantly so need to be answered by sinking, reducing DPS.

Siren could do with less ally damaging potential either by size reduction or nonally colliding weapons. I don't know about you but I fucking HATE using these things in any significant count. Past 5-7 they tend to just smack each other until dead instead of enemy units, likely accounting for how massive they are.
