Well, seeing a part of FF16's use of Eikons, I can see where some of that idea went into each other for that and XIV's summoner.
>Level 90 summoner
>Can only summon a measly 5 summons.
I worry that SE will use the caster DPS slot for 7.0 to try and steer the ship, but it's going to put them in a lose lose situation. If they don't do anything for the concerns, then people are just going to jump ship and consider it a dead job, but if they do a drastic shift and don't include any new caster, then people will assume they used the spot for the sake of it.
But summoner needs the other 3 primals to liven things up a bit. Hell, make any support or utility based on a summon's "skill" as well. If there's a primal that would fit for keeping the rez, then there's that option as well.
