So, I am clueless about healers, but still was playing around in Ariyala and when I poked the BiS Solver it showed me the Weight stats like with all the other classes... but here is where the question prompted on my mind...

What are these stats weights standing for? DPS, HPS or both?
With how important Crit seems to be for SCH heals wise, how come the weights are the same for the 3 healers across??

Are these the current weights even?
Crit = 0.204
Det = 0.325
SpS = 0.178

Thanks for the help!!
