I personally don't mind the size of the summons, I just wouldn't like it to look like something that reminds me of Legend of Legaia 2: Duel Saga's Origin summon designs.

It's pretty disappointing for FFXIV summons reminding me of summon designs from a 2001 PS2 game. Although I think Garuda-Egi is pretty much the only one that needs to be redesigned, since it has pterodactyl wings instead of wings with feathers, like why? I've made my peace with Titan and Ifrit-Egi.
