In all honesty where a paladin has block they need to make warrior the hp / parry tank that would solve all of the issues as far as mitigation is concerned without changing the way the warrior is played. With that they also need to give warriors better cool downs in line with the paladin. Beserk is useless, bloodbath is useless, pretty much all wrath abilities are useless because you are gimping yourself to use them specially in a raid setting where healing is intense.
