shadowblade dance killing spreed if you can use them at the same time? did they give rogues warrior stacks or something? i have no idea..
Edit: the pvp spell power weapons are one handed now, so maybe 2spell power t2? if that stacks something i haven o idea, know that some use the dagger in offhand for pvp power tho
We will be on the PTR soon. Couldn't check it out, yet. We are building spreadsheets currently to actually compare these numbers. From a first glimps on the numbers - it does not look as op as you describe.
