I've been holding off on playing this game because I wanted to wait for a decent amount of content before I dive in. I don't think I started playing Four Elements Trainer until the Book 3(Earth) arc was a thing (although that was because I didn't know about the game until then). And even though I didn't start playing until then, I didn't catch up to the current content until Slave Arc of Book 4(Air) was being worked on due to how slow I am with some games. In any case, as someone who hasn't played this game yet, how much content is there in the game? Is it a good amount, or should I wait a bit longer. Judging by how many changelog updates there are, it doesn't look like there's that much content in the game yet.
