One of the big issues I got with the spec right now is how unreliable both the DR and Shard generation is.
I'm hoping they'll stop this madness, go and give us more reliable Shard build-up and have Chaosbolt/Shadowburn casts reduce the cooldown of DR baseline, with Ripper being the "oh nice, a charge!" trait.
Destruction always was about applying DoTs to weaken the target and then following it up with huge burst. Now it seems it's about how many rng's you can stack on top of each other as a designer.
That said, I'd love it if they could give us a second DoT back that consumes a Soulshard and is talented. Maybe we could replace Mana Tap with it? (PvP Template can be adjusted to compensate for the loss there).
And while we're at it, Channel Demonfire could use both a visual and power upgrade >_>
