Confusion about Backstab Glyph in 3.1

There was a bug that happened between the Backstab glyph and the Deadly Deeds (IIRC) talent. This bug caused all damage, not just Backstab, to do extra damage to stunned targets. This was not the intent.

However, we had been balancing Subtelty for the last few weeks around damage numbers inflated by this bug. We realized when we fixed the bug that Subtelty dps might drop too much. To try and prevent that from happening, we buffed the bonus damage of Sinister Calling.

Rogue talents can be pretty complicated on the developer side. Often one talent has to have a special case to handle the effects of another talent. It is sometimes difficult to detect the bugs that are caused by two talents (or glyphs or set bonuses or buffs or whatever) acting in tandem.

Hope that explains it.

EDIT: Dirty Deeds. Every rogue talent is called dirty, deadly, tricky, shadowy poisons. Every paladin talent is righteous, divine, vengeful, wrathful, holy whatever. Every feral talent is primal, bestial, feral survival. Every arcane talent is arcane X. :)

Dirty Deeds. Teach me to try and answer forum posts on the weekend. :) I think the best one was when I said we were changing Sudden Death when we changed Sudden Doom. Or maybe it was the reverse. Having two Death Coils doesn't really help much in that regard.

Q u o t e:
Are the developers aware that Sub is not the only tree with inflated numbers due to this bug?

Yeah. That was the problem. We nerfed Mutilate on purpose. This wasn't supposed to "fix" it.

We didn't attempt to compensate Subtelty for PvE because not many of them should have been running with the Backstab glyph for PvE unless you are really struggling with trash for some reason.

Some rogues do use Subtelty for PvP. As I've said before, it seems more popular in Europe and Asia than in North America. One article I read suggested that the build is super-dependent on coordination with your team members and tried to make some kind of cultural connection to that playstyle, but I get uncomfortable trying to characterize people that broadly.

Q u o t e:
The issue is, at this point, most of the wow community thinks the rogue class needs to be entirely redesigned from scratch?

Pretty sure I can find a post like this for all 10 classes. Since we haven't yet really re-designed a class from scratch yet (the paladin changes for LK are probably the closest we will ever get), that is probably sufficient evidence that we disagree. If you dislike a class' mechanics so much that you wished they worked totally differently, it's possible you are playing the wrong class. :)
