Keep opportunity costs please.
I'd even prefer to see more of them instead of less. They require decision making and weighing your options, they leave room for optimization.
Yes, using lilies or af heals is a dps loss over other ogcds but it's something you gladly accept when other options are even more of a dps loss like having to cast succor. Trying to find that sweet spot where you can cast as much ED as possible without simply dumping all the responsibility on the other healer is perhaps the only thing that's still fun in a world full or broil, broil, broil..
