Also, such a long CD to prevent it from being OP, sucks up that mastery slot the whole while. It's usually better to bring heal. It is, however, very useful for initiators, in case you accidentally overextend or are focused early, you can quickly get back in the fight. (I find it especially useful with Shen, if you save your ulti you can bait the enemy, revive, and ulti back into the fight.)
