I never understood why Alexander and Odin were made into astral flow avatars not only is it an unnecessary requirement, but in addition if they were added as regular avatars they would have still received an astral flow ability just like all our other avatars. I think that instead of making new avatars Square Enix should focus on these avatars to make them a better part of the summoner arsenal either way all their abilities and movement data is already in the game so how hard can it exactly be. Here my framework of how I envision these avatars being reworked.

~~~Other Information~~~
1.) Unlike the other avatars attributes that are very similar to a black mage or white mage, odin takes the attributes of a dark knight making his attack power much more suitable, and alexander takes the attributes of a paladin making his defense much more suitable for taking damage.
2.) Alexander avatar functions similar to his prime version meaning that he's mobile; however, his auto attack power is quite low comparable to carbuncle but his bloodpacts still pack quite a punch. In addition Alexander is also the only avatar to have 2 astral flow abilities.
3.) Odin has no single target bloodpacts, all his bloodpacts are area of effect and cone range making him quite different from the other avatars, only his auto attack is single target.
4.) As you might have noticed the summoning cost is similar to the other elemental avatars; however, they have a much higher Perpetuation Cost that is because they have many addition benefits that the other avatars do not, and I felt that the high Perpetuation would make them hard to maintain by low level summoners making it unwise for low level summoners to use them in order to keep there powerful image, but they still have benefits for low level summoners.
