I can't believe there are people that would actually complain about this.
Well the original post did make no mention of having a preview for normal players, that was added later.
For me the problem has 2 sides:
Some of these creators are just bad actors. I've seen streamers try to buy duped ottos boxes in shady community sites, for example. And they to this day still get developer interviews and giveaway codes.
And secondly, these creators being paid by SSG and having to abide by some unknown rules, while being under a NDA so we will never know these rules, frankly to me that makes them not trustworthy on any things related to DDO. Their reviews are only useful if I wanted to see what a particular cosmetic looks like.
The problem is not them getting one day earlier access, but it was the implication that this might be a creators only preview. I don't need to be on the preview server myself, but I really would like for people that are more trustworthy to be able to get access.
