The way I understood those changes to egi's, summoner would become quite buffed. The thing Devs should change with egi's are their AI. Make ifrit automayically move away from AoEs so you don't have to spend a GCD to throw sustain constatly on ifrit, reducing your dps.

Also they should take off the radiant shield off and put some DoT ability there, Duration for example 21 sec and CD would be 30-40 sec depending how it would balance ojt to not be too weak nor too powerful.
