Protadins need another cooldown

Warriors have last stand....
Death Knights have Vampiric Blood ....
Druids have Survival Instincts....


All of which are the same panic buttons on short cooldowns, and Paladins still don't have access to a similar ability. You cannot say Lay on Hands matches them because it's cooldown is 5x longer, and even if it was the same amount, Last Stand still outperforms Lay on Hands.

So i'm asking, can Paladins expect a panic button like Last stand, Vampirir Blood, and Survival Instincts in the future? How can you justify all tanks being equal when such a gap is stll present?

Thankyou...
