Looking at the specs, the only real issue that will come out of this in the end will be the 15sec long warriors Juggernaut skill, the horn of renew 2sec invulnerability and the ability to make the both these skills cool down extremely quickly (heroic churro haste, ebon armor haste and Juggernaut mastery).

Almost the same can be said for mages in terms of invulnerability and damage reduction.
