So wait for all the people saying I should put more focus on using my OCDs; if using them is the focus of my kit and my GCDs are my emergency/damage buttons, how is healing harder? Cause I've seen people say that last expansion you could get away with doing the same thing to the point you didn't even need to cast a cure spell.

This is also seems built around the idea that nothing will go wrong with the other players. I'd rather hold onto something for 5 minutes and use it when it's helpful rather than throwing it out each time it's off CD and only getting a minor effect out of it.
