Thoughts on Knight (Tanking)

Unlocked Knight last week, finished Cryomancer and started putting points into Knight this week.  Tried an HT tanking with Knight a day or two ago with maybe half of the effective tank talents and didn't really care much for it (switched back to Paladin after a not-really-tanking-related wipe on the last boss).  Did an MSM earlier today with a few extra talents and abilities I didn't have before (most notably, Barrier II) and it went much smoother.

Barrier II is the real make-or-break-point.  It was actually just recently nerfed but not to the point where Knight is inviable.  The recent patch reworked Inspiration (previously, the diminished Willpower regeneration from Barrier is removed for 6 seconds after using an ability that consumes Willpower) to Counter-Grip (the bonus effect of Barrier II lasts 1 second longer and Lunge restores 2 extra Willpower).  The important component of Barrier II (that's missing from regular Barrier) is that it doubles the damage reduction (30% to 50-55%--depending on if the bonus takes Rockwall into account) for 4 seconds after using an ability that consumes Willpower.  From what I understand, with the right talents you could maintain a very high uptime on the Barrier II bonus due to enough Willpower regeneration which is now a bit nerfed.

Frankly, between a competent support, judicious management of the Barrier II bonus and Tantrum/Resolute Defense, and Whiplash being an OP-as-fuck underdog ult for backup, you should have plenty of sustain to survive any fight a Paladin can.

Which is better?  Eh, I dunno yet.

It's hard to peg either one into a role yet too.  For example, Knight has much better AOE options but no AOE taunt.  Paladin has a low-cooldown, on-demand emergency shield but Knight has constant damage reduction.  Paladin and Knight can both get 4 and 3 seconds of invulnerability with a 16 and 15 second cooldowns respectively (with varying utility; Paladin can extend that invulnerability to allies, Knight can reflect a huge chunk of damage).  Neither seems to have a particular advantage at tanking single targets.

I feel like Knight is much more safer at tanking, but I also feel like I have more control over what's going on as Paladin.  So we'll have to see how things go as I finish up Knight and play around with it more.
