In Anti-Rush instead of having Clissa for that I choose a Rogue, Monk, and Ninja instead (.... stares at all the fox spirits... I'll have you one day!), and for Ramp I choose another Valkyrie to take the role. Allowing that Valykrie to become a Geirolul better fitting that role, and Clissa to become a Reginleif to better fulfill the ganking role.
I think there was only one case in which I had a single unit fill multiple positions and that was simply because I didn't see any value in the other options. I believe that was Koyomi as both an Armor Breaker and AoE Rear unit. Which I suppose the example Odette would do that same thing.
