While I was doing some English to French traduction related to their "Dino Dossier", it reminds me something interesting that I quite forgot since I started to play:
The Megapiranha dossier said " ...a tamed Megapiranha is best suited as a guard."
I wonder when they actually plan to add that feature into the game, since it would totally be a game changer, depending on their stats, for the early ocean exploration.
This is without saying how awesome it would be to build an army of those little annoying Armor breaker!
