Honestly I think they should just get rid of Egis and have them play more like traditional Summoners. As in dps normally and build up a gauge to be able to summon creatures that either do an action or stay out for a bit (30 sec to a minute) and be able to augment your abilities.
I honestly hate the way the egis work since when I’m trying to use abilities I have to spam that ability in order to get it to go off. As for the Physick working with Int thing I don’t really care if they do that.
