Not at this point, I would use them as proxies. Pprobably as expansion of lizardmen army:
Fishmen warriors = lizardmen warriors
Crabs = lizardmen on cold ones
Sirens/mermaids = could go for a myhological greek game as a special rule or umpire unit
Lobster monster = also for special rule scenario or umpire unit.
Tritons = also for a mythological greek game as special rule or umpre unit. (not made yet)
Maybe if I made a solo campaign I could playtest some sort army as Critters of the sea, or Poseidon or something. Right know rules are not my priority, because those days I am not playing at all.
Does someone have any ideas about more type of units that could have an army like these?
