I understand wanting customization options but it really doesn't make much sense to use a tiny Carbuncle construct to do the same things as the level 90 summons. In all games in the series the progression of a Summoner to a more powerful state is punctuated by the acquisition of stronger (and in most cases larger) summons. A massive Carbuncle could make sense but a tiny aetherial creature doing things that far surpass the amount of aether it's made of is silly. I would love to see an Embellished Carbuncle model. Something beefy and detailed and ornate at later levels as an option. The Carbuncle Mounts available on Mogstation already exist as an example of this. I'm really not sure why they didn't use these Mount Models as an upgrade for Carbuncle already. Taking them a step further and adding even more visual flare for level 90 would be very welcome in my opinion. I just don't think baby's first Carbuncle is an acceptable replacement for everything we summon at 90.
