Can't Ise just bomb the darned place and literally like evaporate everything including all cuccos. The number of cuccos is irrelevant if Ise just uses the Inexstinguishable Flames (which can envelop an entire island) or just use his cannons to blow everything up (like he did in the tournament) as they will all just get practically erased.

Five keys is even better than just three. This way it's better summarized and people won't suffer looking for every single thing within the profile.
I can't really think of something that would separate his 3rd and 4th keys. The 4th key is just Dragonification, Igneel's power, and Dragon Force. They could be one for X792 but idk what to do about the fifth one, cause that just seems like making a new key because it's stronger than the others.
