I recently respecced to SM/DS.

Reason being that we got hit with the nerfbat again (Impr Drain mana nerf ftl). So I decided if I have to respec anyway I could very well try out a different build for some time (only 15g respecs

).
I'm curious how it will do next time I do Onyxia and Molten Core. It's a kind of weird not having any points in Destruction though. I won't miss Impr Shadowbolt much (I only have the 5% base critchance + some from int), but Bane and especially Shadowburn are kind of hard to miss. And no more inf mana really is weird.

In normal instances I guess I'll do about the same damage if I sacrifice my succy (should more or less make up the loss of Bane), maybe even abit more if it's not just the pure SB spammage, but in really long fights I'll probably take a dip, since DP > DS(VW) for pure mana regen. I do expect my survivability to be abit better, since I'll be even less reliant on healing.
So far I've only grinded abit. Saccing the VW for health regen and enslaving a demon is a fun and fast way to grind. I also noticed my succy holds aggro a little bit better, and of course summoning a pet in .5s is nice as well. I haven't been ganked by a rogue yet though, so I'm not really sure how well it'll all work out.
All in all, it's nice to try out a different build for a change, but I think I'll change back to my DP build eventually.
