I believe everyone who's already raised has made the case, but I'll just echo some of it here with a direct answer to OP.

Yes, we are very unhappy. The changes made are nonsensical in its current form, from the kaiten removal to the potency shifts to the overall speed and feel of the job now. The way SAM plays now, I heard some other comments stating it feels like a slower MNK now. Just mindlessly droning through the GCDs as the finishers barely make a dent. The only difference is we have an oGCD to weave whenever so we aren't bored... except we are. We are bored, and disappointed.

The job just isn't right. Overall numbers being roughly the same is not a good enough excuse to leave it as it currently is. If the overall damage that they wanted to change is really not different, why did they change it at all? That's why we're so annoyed with it.

It's like someone took all the stickers off a rubik's cube and rearranged them to where the colors can never all align on the corresponding sides. It isn't broken at its core by any means, but anyone looking at it can see it shouldn't be like that.
