Don't really nowhere else to put this, but pretty much Bladestorm gets reduced to 400 damage with armageddon. (so think about it)
Feint (50% aoe damage) + cloak glyph (40%) damage
Wow feel so dumb for the double post so sorry.
Okay I can go into more detail about this now, pretty much the glyph of cloak of shadows allows 40% Melee damage reduction (Duh) and I didn't think about this at first but Bladestorm is considered an AoE so feint is 50% damage reduction against AoE (On a 10 second cooldown). So I decided to try and see if they both stacked turns out if they do.
The damage reduction is phenomenal. This may sound like common sense to some and I may be completely retarded, but it was news to everyone I mentioned it to. Once again so sorry for the double post
