More summons for 4.2 or at least 4.4
I'm talking the last 3 Elemental Summons and maybe Pheonix, Alexander, or Odin. Or maybe take a new twist on the story and learn how to summon Voidsent gods like Diabolos, Cerberus, or even goddess of the Voidsent, Cloud of Darkness herself. There are so many good ideas still out there and new twists, FFXIV will only die once there are no more interesting twists and point of views to see.
(Continuation from previous due to a 1000 word limit)
Leviathan Egi - A globule ball of water Aether withe the famed serpent coiled around it. like a constrictor. Healing Pet.
Ramuh Egi - A billowing cloak of purple with a tree root styled beard, small wing like appendages on the back with bright lavender eyes and a lightning bolt at the end of the right sleeve. Attacking Pet.
Shiva Egi - A chibi sized feminine elven shaped crystal crowned with a tiara of icicles and with a large blue ribbon twirling around the body like a feathered boa. Tank Pet.
Pheonix Egi - Not so much a summon pet as a one time per battle skill that will resurrect you by dissipating your pet to bring your own consciousness to the land of the living once more in a blazing inferno of blue flame and feathers.
Odin Egi - Not sure how this would work but could be like Pheonix Egi, a skill that clads your body in Dark Aether like smoke giving you skills similar to the Dark Divinity.
Alexander Egi - Time and Light based angel castle mech. Enough said.
