You can't have such a big time between announcing the patch and having the patch go live IN THIS GAME. PTR and beta testing are methods that are applicable to games with a bigger playerbase, like LoL. At this point there's like 1-2 players on PTR at any point, if any. And they're not even there to test new REs, just to test builds that are already playable on live as to not waste currency. You didn't provide a shop or any quick way to get the NEW REs specifically, what's even the point of this fiasco?
Meanwhile look at something like Dota2 where there's a hero reveal / patch notes come out and BAM you can play exactly that right away. I feel that'd be a better strategy for this game instead of what you're doing now. By that I mean just dumping patches on live and hotfixing the things you inevitably break. Because when you do what you're doing now, any hype for what is to come dies
