Yes. And? Are you we not allowed to be critical of content and also enjoy aspects of it?
I have made a bunch of threads outlining how to improve in RSS and what my experience was like in RSS overall. There is a lot to be frustrated with. It has made some aspects of the game worse for PvP. It has also made something’s better.
Here is one of them.

Again, my issue with people like you are the ones that complain about gatekeeping that doesn’t exist. No one is preventing you from doing arena. RSS didn’t fix that. Instead, as the forums clearly show, we have a whole host of new problems that RSS created. Some of those issues might find fixes, but many won’t. That doesn’t mean the content isn’t successful or people don’t enjoy it, but it has plenty of problems.
