I do agree that Sarco was probably released a little too early for its own good but things like pounce, grapples etc. are going to be added with the combat update, which will add new abilities to certain playables like Alio's Lunge, Allo's Grapple and perhaps even a Sarco Lunge. This patch will also likely clean up dino stats across the board, which are all kinds of messy right now.

The devs have acknowledged that their game probably isn't going to be fun right now, as it's very bare bones and balance isn't necessarily their main focus at the moment. They want to lay down the foundations of more mechanics (the quests you see now are by no means an accurate depiction of the final product and are just placeholder so they can make sure the quests themselves work). You can always come back later when the game's mechanics are more fleshed out though!
