SE, don't overthink Summoner 7.0. Just give people what they want. Just do it.

For example, I mentioned earlier that one possible way to loosen up the job's rigidity is to reverse the way gemstones work on the gauge. Ifrit/Titan/Garuda do not require gems; they have cooldowns and generate gems, and its Bahamut/Phoenix who require 3 different gems to be summoned (and you start instances with 3 gems).

This. In addition to being much more natural and sensible to think of it: because it doesn't make sense that your strongest summon unlocks 3 weaker summons but it should be vice versa, it clearly also makes rotation more natural and makes the rotation completely non-rigid to delay the burst phases when mechs require it. This for the basic rotation of the smn would be a healthy touch. (And the fact that the designers didn't think about it makes me think badly). Personally I wouldn't start with 3 gems already, but I would prefer an ogcd with a 2 minute cd that fills the gems (this would allow, playfully, to potentially vary the rotation)

I always said the summons should function like FF7R. Summon comes out and you have no control over then. They do their own thing. They single target attack when it’s one enemy and if two or mor they aoe. Then after maybe 15 seconds they perform their ultimate attack and leave. Just my opinion.

my personal opinion, I prefer that my summons actively influence my gameplay, and that they are not just dots. If having all summons actively controllable is difficult, and I can understand that, I would like at least my carbuncle to have this feature. If with 7.0 they get rid of the thought by giving it an automatic attack and stop, practically haven't made the class more playful and personally it would annoy me.
