I know some of you guys have been going tank specs in WFs, but in the majority of cases there is no reason for people to attack you since VK mana draining is no longer threatening and you just get ignored while your team dies.
However... with the recent fixes to subdue, it's viable to be a PVP tank that actually helps their team considerably.
That's the spec I've been testing most of the day today (around 15 WFs total).
The basics behind the point spending and use of the spec are this:
-Concussion does not proc subdue. Cracking skulls (14 warlord) and incite (32 reaver), however, do.
-Both sergeants order and grim lure also proc subdue.
-What you end up with is 2 single target taunts on 8s timers, 2 aoe taunts on 1 min timers, each that proc 15s of damage reducing awesomeness.
-Your aoes reduce others strength, and you can put infestation on especially heavy hitters to reduce damage further.
-Try to use the heal debuff on tertiary targets that are being focused by solo DPS players who aren't warriors. Multiple players heal debuffed and taking damage = much harder job for the healers.
-Use cast on target of target to put guard on whoever is being focused. I also have a macro for it that I use for my squishiest party member (usually a mage or low rank cleric).
-When you have just used an aoe taunt on all the DPS and don't need sergeant's orders for a few seconds to reduce damage, use it as an interrupt on heal casts. You can also use it to pull healers out of LOS of their DPS, causing them even more issues.
-Always use your fear off cooldown, preferably on a healer when another player is being focused down.
Basically when played well, you actually cause their team so much trouble that they MUST focus you and try to kill you. With all the damage reduction in this spec, wish them luck. If they don't focus you and your team has a couple of healers, nobody is going to die.
There are a TON of cooldowns with this spec, and I had to add 5-6 extra hotkeys on top of my normal 15 or so. For this reason, it's also complicated to play and requires a lot of concentration and multitasking. It will take me quite a while to master it...
Good luck and enjoy!
