STOP!
Paladins still have Block, which warriors do not get. Warrior damage intake is going to be very skill dependent. But all the skill in the world wont save you from a large crit in Coil in those windows where our new DR effects go down, and we don't have any other DR skills in effect.
The boosted HP will mitigate those strings of downtime, so we don't get one shot for not pulling off a flawless rotation of overlapping Damage Reduction.
The increased Healing taken is there so Healers are restoring the same percentage of your Health Bar as a WAR or PLD, avoiding the WAR becoming a huge MP drain to try and get back to safety levels.
The way i see it, the PLD is still the premiere damage reduction Tank, as its DR effect is always on, with the cooldowns to burst out some very heavy reductions, while the WAR is now capable of reducing its damage taken in spikes. We were never really a "self heal" Tank because IB was so limited in its usability. Restoring 2k HP every 20 or so seconds isn't really effective healing, especially as the Tank is receiving external healing, most IB's went to waste as pointless overheal.
It was great when it saved your life, but if it was saving your life, something went wrong on your healers end.
