I was wonder what do you think of those 2 that left of the 5 champions?

Oona could be nice if she makes Melees attack first, Baltasar make cannons attack weakest? what do you think? what they could be useful for if they ever came to settlers online as well as the first 3 generals?

Meet them in real:
