It is obvious that not all daemons are usable in combat, a third of the Ogres can fight, and only a quarter of Pixies had the ability to even wield a weapon.
The Combat Pixies were a minority, most of the newly evolved Pixies were either Praeries which made them sound like some kind of landscape variation, but no, these Praeries are Pixies not fit to become combatants but is very good at assisting the horde.
Those who evolved like so wouldn't have any more chances of becoming a Legend Tier unless a major event happens and triggers something that will cause them to either level up quickly and receive LE in great abundance or if they mutate into a Greater Variant.
Mutation does not happen often but when it does, those who benefit from it would become stronger.
