Oh you are so wrong there. I am a big contrarian to this 1-shot combo-wombo you die business. It’s annoying to heal, in particular because there is nothing you can do. No amount of L2P can stop that. Just pure RNG and nothing else.
And there are better alternatives, which I have suggested already in other posts.

And yeah… that’s right. As incompetent as thinking that not allowing Dinars for LFR players would not create massive backlash. 
Pruning healers to oblivion? Yes they have. 4 times already.
And if it is? Will you do keys with me?
