Why is Carth Onasi in Ships Hard Nodes?

My only issue is that Carth is on ship node and only because I believe the difficulty of the farm should represent the quality of the character. Carth is a B tier character at best, more likely a C tier character. He's someone who should be in a store if they didn't completely right them off, or a mid tier Cantina battle. Instead he's in the hardest to farm nodes in the game. Who cares about what you can unlock with him, or what ship he may pilot in the future. His character just isn't very good for where he was placed.
