The short answer is that statting critical hits is generally better than statting chance if you're looking to improve your average heals. The decision isn't a function of anything besides your current water damage + heals and critical hit rate because you don't have to deal with target resistance, backstab, etc. Here's a easy way to think about it: Say you have 150 stat points to spend, you have 600% in total water damage plus heals, your critical hit rate is 30%, and your healing spell heals for a base of 50. The spell will heal for an average per cast of 0.7*50*7 + 0.3*50*1.5*7 = 402.5. If you spend all your points into crits, resulting in 10% more crit, the spell will heal on average 0.7*50*7 + 0.3*50*1.5*7 = 420. If you spend all your points into chance, resulting in 25% more water damage/heals, the spell will heal on average 0.7*50*7.25 + 0.3*50*1.5*7.25 = 416.88.Loved the math you did there.
But, is that a valid comparison? Since +water damage is fixed, while +crits is still a probability.
