Tank synergy other than slashing!

For Intervention to be better than a 4k Blackest Night (10% a i290 Dark Knight's 41k hp) it requires the attack to deal 40k unmitigated base (10%), 20k unmitigated with Rampart (20%) or ~13k with Sentinel(30%) within 6s. Considering that Casters have about 26k and melee have about 30k I'd seriously disagree with your assessment.

Considering that those kind of skills are only useful on hard content, since using them on normal situations (aka unneeded scenarios, like using Mantra when healers can easily top people without problems) is worth around 1 heal less, Intervention is still king. For example on a Tyrfling from Zurvan EX Intervention is far far better. We are considering uselfuness on hard content, and there Intervention scaling is much better. The scenarios where a tank can eat even 40k damage inmitigated on the span of 6 seconds are not so rare on hard content, otherwise tanks would never need to turn on tank stance/use defensive cds to mitigate certain atacks...

Im not sure I see how Paladin is supposed to be so far ahead of all the others. It's gonna have some burst moments and some defensive tanky moments, and the rest of the time it's going to be on recovery. Drk is gonna keep some sustained damage going out, depending how much mp and blood you can keep using. I havent run the math but I can't see it being the only thing necessary

Between Requiesqat 12 seconds heal and spell damage buff and the Fight or Flight buff now lasting 30 seconds with a cd of 60, not counting the damage increase on paladin combos is not hard to do the math that pala is self buffed most of the time thus boosting his already buffed damage by a lot. Right now some maths put the Drk doing 2-5% less than Warrior while Pala doing 20-25% more than Warrior xD
