Non Summoner Here..... But my wife plays as a Summoner...

While I don't think there is a need for a total revamp on the Summoner, I like the way it is.... I just kinda hope that the EGI's get balanced out for their utilization in the future....

Instead of seeing a summoner with Garuda out at all times during End game.... it'd be nice to see them have to alternate between their summons in battle... Im not sure if that means to tune a fight or two to optimize this, or tune the EGI's so they are all useful

Yes... Titan is a tank, and their is no need to pull him out unless one of the 2 tanks die in end game situations, and if this happens, its probably a wipe anyways....
But... how bout a situation where a primal battle, or coil raid switches from optimum range assault to optimum melee assault... and a good summoner would need to switch from garuda..... to ifrit..... back to garuda mid fight... and swiftcast would alleviate the need to casting time...

Maybe Leviathan comes in as a healing EGI.... so after the big aoe phases like garuda after the jump, titan after the heart... king mog when he summons.... leviathan for 45 seconds would be ideal....

Either way... its kinda dull seeing garuda shooting yellow spit for 10 mins... i'd like to be wow-ed by a cameo appearance of leviathan..... and hopefully this type of alternation will be expanded in the future...... a vanity green ifrit? a complete optional egi like mog? fenrir as an average summon but has a relic weapon like ordeal to achieve, making it a vanity commodity?
