Champion type dragons in Battle Arena

[RhodryMaelwaedd]

As all pure champion dragons (not the hybrid types) are unbreedable, does it even matter if they're Rare, Super Rare or Ultra Rare? I mean, don't they all have the same strenght in the Battle Arena? As the rarity order in the Arena is: Common - Rare - Unbreedable - Super Rare - Ultra Rare.


(Edit: sorry, hadn't noticed there already was a champions' strenghth topic. Question still stands though)

Glasswing and Valiant are Ultra Rare (& why they are the best of the best)
Black Knight and Immortal are Super Rare
Last time I checked, all other champs were Unbreedable
