Facts:
Arms warrior’s only major survival kit : Die by the sword 2min CD(1.5 min with 2 points invested in talents–>mistake here. it’s 1 point invested so edited here. DF talent had 2, TWW is now 1): Parry chance increased by 100% and reduces all damage you take by 30% for 8 sec.
Fury warrior’s only major survival kit : Enraged Regeneration 2min CD: Reduces damage taken by 30%, and Bloodthirst restores an additional 20% health. Usable while stunned or incapacitated. Lasts 8 sec.
That is it.
Spell reflection (25sec CD) is most of the time used to reflect just that - a single spell (and not even all spells can be reflected or does damage back to target) and yes it reduces magic damage but you still take damage which can kill you or leave you on the brink of death. And yes that is even with Defensive stance on.
Impending Victory 25 sec CD: heals you for 30% of your maximum health.
ok let’s now look at paladin
Divine Shield: This is a total immunity for 8 seconds.
Shield of Vengeance: Creates a barrier of holy light that absorbs [30 / 100 * Total health * (1 + Versatility)] damage for 10 sec.
When the shield expires, it bursts to inflict Holy damage equal to the total amount absorbed, divided among all nearby enemies.
Divine Protection: Reduces all damage you take by 20% for 8 sec. Usable while stunned. 1 min cd? wow
Blessing of Protection : makes your target invulnerable to all physical damage for 10 seconds and also removes all physical debuffs from the target.
and many more utilities which can even protect others.
Wait? he can heal on demand??
Lay on Hands : Simply heal the target for an amount equal to your maximum health. Can be casted on yourself
Comparing DPS warrior’s defensive CD to Ret Pally’s is an insult to paladin.
