I wish they would remove carbuncle, because I think that would be something of a wake-up call to everyone who is "just now trying summoner" and finds no problem with it. Removing carbuncle, a core part of the class and lore, makes it blatantly clear that the new summoner is just not fun enough to stand on its own. Plus, you can bet people would be rioting over losing the cute pet the same way SAM mains are rioting right now over the 6.1 changes.
