As another who also learned that there is no medicine for regret, I can relate as I just transmuted a bunch of green and blues enough to get me 14k stones only to pop in here a couple days later and find out another double transmute even is on the way soon in a thread leaked by someone with vip acces. Thank god I stopped there and didn't continue with purples,
Well, a moderator in the thread said it was coming. Then the guy who posts official updates said he was mistaken, and they don't plan on doing it again. So who knows!
I think the dissemination of information is extremely unprofessional with this company. So much success is predicated on long term planning, and you need to follow 2 social media and four chat applications to apparently stay informed, and then you can buddy up with devs directly for special insider knowledge it seems.
Nothing should be leaked, until it's ready to be patched on PTR for testing and feedback, or they have a formal patch date for game. All of it should be posted on their Forum, twitter and facebook
