Like someone else said this is the Internet so this ain't nothing new, but people have really wrongly internalized that offering feedback or criticism is automatically something negative and bad and hateful.
Likewise, I want to be more excited for Pictomancer, and the gameplay video was very underwhelming for me, which is why I've been giving feedback on the visuals. This is not out of hate for the job, this is not because I was expecting something entirely different like Green Mage, this is because I want it to be better than it currently is, because I know it can be.
Partly because FFXIV has some really good VFX already, and I was surprised that the Pictomancer ones weren't of the same quality or general art direction, and partly because, as has been shown in other threads, other games with similar classes have achieved visuals that are a lot more compelling than what we've seen so far.
The most important thing for an artist is to understand the nature of criticism and feedback, be open to it, and listen to it, even if you disagree with it at first. This is the one skill you learn in art school, and this is the main way you improve yourself as an artist. Subjectivity doesn't mean that it's someone's opinion against the rest of the world, but rather that there might be some truth in everyone's opinion, and it's up to the artist to find that truth in the feedback they receive, in the interest of perfecting their work.
