New flanking Strike dont remove defiant
Flanking Strike never removed boons like Defiant. Larcenous Strike only strips boons that you, as a player, can attain. For example, you can strip Might, Fury, Aegis, Swiftness, etc.
Another quick note: Most bosses will show boons that look similar to ones that you see on yourself or other characters (boons that have the same picture as Might, for example) but if you hover over them, they may say a different name (Crystal Might). These boons cannot be stripped as they apply a different percentage of additional power to that specific mob.

Then was a bug? each time i was using S/D flanking strike it removed 1 stack of Defiant.
Maybe something was hitting the boss at the same time with a CC effect removing defiant stacks? Or maybe the proper boon removal was considered CC and defiant was removed instead of boons?
