I think the (potential) problem is that if Shard Shatter looks at Rare Resourcing (because you are Shattering a rare item), then people who invested in Uncommon Utilitarian have wasted their points - because now you can take a piece of rare armor, Disenchant it into a high quality shard, and then Shatter that into high quality dust.
The other option is, Shatter is unaffected by your Designated Disenchanter sub-specializations, or is affected by all of them. But that feels like it’s going to have issues, I just can’t quite pinpoint them.
The way I can see this working is to have Shatter benefit from the sub-specialization of the product. So you Shatter a shard to get dust, the quality of the dust is improved by your Uncommon Utilitarian, just like if you were Disenchanting an uncommon item. And similarly, if you Shatter a crystal to get shards, the quality of the shards should be improved by your Rare Resourcing. Which leaves Epic Escalations to benefit only directly disenchanting epic items, but I think that’s fine.
I have some concerns about how Shatter is going to interact with reagent quality, so hopefully Blizz keeps an eye on it, and is ready to react a little faster if something seems out of whack…
As mentioned above, is there any recourse for players who invested their knowledge points heavily into Uncommon Utilitarian now that the game state is suddenly being changed? This wasn’t a bug fix or anything, it’s introducing an entirely new mechanic. Before this change, Uncommon Utilitarian seemed like a worthwhile early investment because disenchanting green gear was one of the only way to generate Storm Dust. Now that Storm Dust will be much more abundant, players who chose to invest a large bulk of their professions Knowledge Points in that path feel robbed.
If you get lucky and get Finesse to fire when you get one. I’m only using Green tools with a perception enchant. Sitting at 10% Finesse and 21% Perception for Bismuth.
The goblins hopped on this one quickly.
