Other Playable Characters

I really wish the other playable characters had more involvement with the game. I can understand having only Kliff for the main story (it's a bummer, but whatevs). However the fact that most of the puzzles and a big chunk of side missions are Kliff only, makes me. ot want to bother with the others if Im constantly having to switch back to Kliff. While like I said that Kliff-only main story is fine, it should've been balanced as the other can do all the side content as well. Like Damaine's shield throw could've had the same effect at the axiom push for puzzles
