Well, while Alim base lagacy units from polls, they do have to consider an expansion of a unit's lore as well. If one's lore reaches a dead end, it's unlikely that they can get a new 7*.

This time, it's another kind. Omni evolution uses the alternative path of a lore, so units who have a dead end lore may have an omni evolution (remember that it's not limited to only 7* units). However, their lore must also be able to generate a "what if" story as well.

In this case, I might have high hopes for Zedus. because there's a "what if" story of Gazia did not betray Zedus and decided to co-operate.
