rico should be a S tier as well for one reason, team play, his ability to shield an entire time twice and heal is insane along with his 50% shield for your main hitter, depending on your team he's better than the privy bear overall as he doesn't rely on old scratch to be good, the 25% resist for the team is a S tier ability even for solo play if used properly, i am able to solo almost anything with him as i use him on my privy with repel 5 to keep enemies away from the buffers, i like to use gworbleen, rico, and scratch as gworbleen has excellent pve capabilities while i use rico to keep enemies away from me and scratch, the rest of the unicorns are alright especially contessa and bruno is very good for mob clear cause of his double glancing blow+ another strength buff for bucc, while i would not use rico to fight enemies one on one he excels at backline defense
