Or is it to late for feedback to be relevant anyway?
They said they wouldn’t make any more posts like that now that the alpha was out and the HT information is openly available. There are still feedback posts in the exclusive alpha forums: Feedback: Demon Hunter Updates
I suppose they consider that if you don’t have alpha you have no right to give an opinion in an official post. 
The funy, or sad, thing is that they always say that they prefer written feedback but they invite content creators who mostly make videos to the alpha, and then they go to the Discord servers of itch class to look for opinion summaries. If you look at the alpha forum, hardly any participate.
