Personally I agree that it is just silly. But when you look at it from Blizzards point of view, it is at least consistent. They want to change affliction because they don't like that you have to use an addon to make it playable, so they will certainly not like the idea that you need an addon to keep your bags clean. Destroying shards manually is an option but I would not call it pleasant.
If they want to make our lives easier, why not offer us the current add-on functionality from the normal UI, and make the number of shards or the bags they go into configurable. As for the SL removal removing my need for an add-on: they're dreaming. I go from 5xhaunt, 4xUA, 4xImm, 2xCoA, 2xSL per minute to the same rotation without SL, and suddenly I don't need an add-on anymore? I was watching 3 timers before; I'm still watching 3 timers. Even the removal of Imm wouldn't help in that regard.
