Glyph of Bugstab
Some testing over on AJ has unearthed an interesting rogue bug. On live, the Glyph of Backstab currently reads:
Increases the damage dealt by Backstab to stunned and incapacitated targets by 20%.
What it actually seems to do on live is increase all your damage versus stunned and incapacitated targets. I tested it myself on training dummies (with 2x [Main Gauche] and a [Lovely Black Dress] and it definitely increases mutilate damage; people in the AJ thread report everything from evis to white damage benefiting from the multiplier.
That makes it a pretty amazing burst damage glyph!
Of course, it’s getting changed to a worthless attempt at a PvE glyph in 3.1 (which seems weird to me, surely they don’t think Shadowdance is overpowered right now?) but unless they ninja-hotfix it you can still take advantage of it until then!
(Sadly, it probably won’t make our hardest matchup much easier)
EDIT: Here’s the official solution – fixed in 3.1, but they’re upping the Sinister Calling damage bonus on hemo and backstab from 5% to 10% so subtlety isn’t hit too hard. Interesting change, since it’s shifting some sub damage from burst to sustained.
