It just seems like there is a big conceptual hole. With demonology there is a "flow" based around shard generation/consumption for spells. But it always seems like I am able to do something productive. You can't be "shard starved" as demo.
With affliction, at least as I've been playing it, unless the encounter is specifically designed to have several relatively long lived mobs, you're going to be begging for shards, or sitting on shards and not casting our core mechanic (UA) until we're shard capped or the one moment we make our move.
It just seems so conceptually... not right in comparison. And especially when they knocked down effigy as a shard generator / damage dealer and knocked down soul conduit. I know Blizzard said they want us to cast UA "every 8 seconds" and I guess not really stack it except for burst, which is what is driving these changes?
There just seems to be a big hole here compared to Demonology.
