We've had another dev blog with accompanying forum thread on an upcoming Heart of Fire change: the concept of salvaging high-end gear (turning it into unrefined astral diamonds) is going away, and instead this gear will now just turn into refinement points like lower level gear.
My first reaction was a proper Darth Vader-like "Nooo!" though I guess in fairness, we don't really know just how bad it's going to be yet. The devs say that they'll add AD as a reward to lots of activities to compensate for the loss from salvaging, but they don't have a history of getting that sort of rebalancing right very often.
It's still going to be a nerf for me either way, because as it stands, I'd often collect gear on the weekend when I had more time to play, and then slowly salvage it throughout the week to maximise my bonus AD from invoking. After this change I won't be able to "save up" AD this way anymore, so if I don't have as much time to play during the week, well that's just too bad.
I suppose I should have seen it coming though, as I've been feeling quite comfortable with my AD acquisition levels lately, considering my casual level of play. One thing I've learned throughout the years is that if something is working well for me on a casual level, Cryptic will rate it as crazily unbalanced at the high-end, and it will be nerfed soon afterwards.
