And I think that's always a interesting mechanic for me to play with whenever I feel for going out as a healer.

DPS classes are more simpler than that : You keep eyes on your positioning, your combos and on your job specific mechanics.
Emnity and health aren't a issue if you have players on those jobs that are worth their salt, and you keep the points above in mind.
