Expressing disappointment that the next step of a beloved series is not what one wanted is not shitposting and, with due respect, the loser part is uncalled for, duckroll (this is coming from somebody who really appreciates you as poster from many years).
Yes, the industry is changing, and yes, we won't go back to the "golden years" whatever that means, that doesn't change the fact that people have expectations and desires, and it hurts when something frustrates you. Expressing that in a forum, which is the only relief to have, shouldn't be something to be mocked.
I would understand your point if this was the OT of this game and people came to post in that tone, that would be uncalled for and annoying. But this is just a teaser thread, and I feel one should be able to express his disappointment in a announcement thread. Then, that person can "fuck on", and avoid every other single thread about the game so the people who are interested can discuss it in peace, but right now we don't even know what the game is about and I feel is fair for every fan of the series to express their feelings.
(Not saying this for myself, I'm interested in mobile gaming and will try Granblue when I have a new mobile, just trying to empathize with people who feels sad about this).
