Sentinels/Marauders, the new 4x DK?

I'm thinking 90% of the time my points will be used on Zen rather than the run speed buff. With Watchman spec you already get a static 30% snare and 11 second charge. I can't imagine I'll have trouble staying on top of people, provided the lack of IWT isn't an issue. Being able to AoE heal 18% health every ~15 seconds plus the 2% on every DoT crit is pretty boss.

The only issue I have with the group is Sentinels can't tank. I wonder how much of a damage loss it would be swapping one Sentinel for a Guardian.

Guardians in Vigilence deal pretty solid damage. The reason why transendense is useful is that 50% or 80% runspeed makes you unkiteable. The passive snare on your dots is imho a waste of talent points. Use your melee snare!

Running the guardian is not a bad idea and I'd consider it strongly if I ran 4 accounts. Basically what you give up is some group healing, a little bit of DPS, and your Inspiration buff. What you gain is an AoE snare, the ability to guard, single and aoe taunt. Here is the thing though, the Guardian in PvP is easier to kill than a Sentinel is, primarily because they don't have all the tricks that a Sentinel has. A Guardian will be slightly more difficult to kill at any one time and the Guardian cooldowns are designed to prolong death rather than to escape it. That said, guard+aoe taunt+aoe snare is going to add much utility to your group. This is also why 4 Guardians is a pretty hilarious team. As far as I know AoE taunts stack. Jump into a group of people and blow 2 AoE taunts and the enemy is doing 60% less damage to anyone they attack that isn't you. Blow 4 and they should be doing almost no damage for 6s. Or rotate them for almost 50% uptime on -30% damage.

If you go the Guardian route, in PvP I would probably take one of the Sentinels out of the Zen/Trans rotation and sit on the 30 focus. Save that focus for a transendence so you can use it when needed to escape combat. Drive with the Guardian and setup a click window over your party frame that guards on a click. The passive healing coming in through Zen/Crits will help to offset the spike damage on any of your Sentinels.

What about 4 Guardians? You could daisy chain Guard and there's a hybrid Shield/Vigilence spec around that does pretty solid damage and makes your AoE snare and Force Sweep both free to cast.

Like was said earlier, 4x anything is going to kill people. I think however that in terms of raw face melting potential, Sent/Marauder trumps the Guardian/Jugg.
