I don't see what's so upsetting. There were talks about new pets, but for a lot of other summoners that was not the case of "fixing" summoner. It came from the current pets being adjusted and the caster being adjusted.

We have no idea how the new abilities will go for the pets. What I do like are the trances, how we're channeling primals power through use to not just give it form but to perform a move. Instead of a 5 minute movie of Bahamut coming out and firing a blast we push it through our bodies.

To me they're giving us a wonderful change. New pets with the same problems fixes nothing except to the users who just want something new and flashy. If that's the case..black mage is the way to go for you. New pets may have been part of the original plan but they got phased out. It's not fair to ask them to inform us of every change in development as it goes through instead release it to the public when it's more definite. It might of bee a possible idea for Yoshi then but things change and they have to hold it back.
