1. When rouse/spur/enkindle is used the egi takes on a bigger form and/or they change into a much smaller version of their original primal.
2. new summons ramuh caster dps shiva tank leviathan melee dps adding glamour only to corresponding summons emerald carbuncle can only be glamoured with garuda topaz only with Titan. It doesn't make sense to have titan or ifrit cast wind magic and vice versa.
3. summon I, II, and III are different class types while picking the egi to summon via the pet window. example- summon I is a caster DPS, summon II gives pets tank ability set and, summon III melee DPS. in pet window you choose a form the egi will take garuda/titan/ifrit/leviathan/ramuh/shiva all those will have a set of caster abilities that are the element of the egi, I feel this could be a better option to use any pet you wish and have it serve the type of role you want it to play. all they would have to do is change the skin of abilities not hard to do.
