Nonetheless, the post Community Manager Lore made today is completely non-specific about what's actually happening. All he says is as follows:
I am going to remain cautiously optimistic that they will not make a bad call, and stack the buff up with some other mechanic. I'm also hoping they don't go down the route of stacking debuffs, as I discussed at length in the previous article. From Lore's follow-up post, it doesn't look like they will be testing anything on the PTR, so live servers will become test servers for whatever they decide to do. I'd be happy if they just reverted it to what it was before, and went back to the drawing board rather than messing around with the season any more than they have already. We'll see what comes to pass.
