SW:ToR Tanking and the Assassin

Disclaimer: Min/maxing ahead.

There has been a hot mess of a debate going on in the Rift warrior forums over here regarding post-patch 1.1 damage specs. I managed to slog through the entirety of that monster of a post and, sadly, come up with very few competitive dps specs. Even after the nerf to BM, it still looks like having a pet is mandatory for pulling the best dps, but 1 or 2 other specs may be close.
(note: BM gains a lot of buffs by itself that other specs only obtain once they join a raid which has a tendency to skew the numbers in favor of BM, but no one knows for sure how much).
I will list the specs in order from highest to lowest sustainable single target damage. Do note, however, that I have not tested these myself since the patch but I plan to do so this weekend. Several people have posted parses in the thread that I linked above if you feel like wading through half a ton of BS and slander to get to them.

EDIT: I just got done testing the first two specs, and the BM spec (on a raid dummy) does outperform the Paragon spec by quite a bit, but you need to take into account the lack of buffs for Paragon. However, even with equal buffs it will parse out lower than the BM spec, but in my opinion it's a great spec for someone who hates having to deal with a pet (i.e. me!). The last spec I haven't tried and, to be honest, am quite skeptical about due to the way that our spell damage doesn't scale well.

NOTE 1: Warriors are very weapon dependent. Yes, you heard me right... not gear, just weapon. This is due to the fact that our attack power scales horribly. As such, it's actually better to take leather gear with a ton of dex and crit on it. Go figure. Hopefully they fix this.
NOTE 2: Adding flinching strike to the macros for the first 2 specs are a definite dps increase if you have the energy for it. In other words, you need to be grouped with a bard running Fervor, or a chloromancer running Living Energy. If you have one of those buffs, you are golden.
NOTE 3: The macro setups are just suggestions. You are better off using them as a starting point only and then deciding how you would like to set everything up. Everyone plays differently!
