I wonder what the forums will look like if we start seeing healers in dungeons with these as their shared role actions:
Cleric Stance
Break
Rescue
Surecast
Eye for an Eye
"Healer please cast protect", "Sorry, I don't have Protect"
"Healer please remove this debuff", "Sorry, I don't have Esuna"
"Healer, why is it taking so long to res people?", "Sorry, I don't have Swiftcast"
"Healer why aren't you healing?", "My mp ran out and I don't have Lucid Dream"
"So what CAN you do healer?, "Oh I can give myself a 5% damage buff for 15 seconds, zap a mob and slow it, yank the BLM out of his leylines for the lawls, make myself immune to knockbacks and pulls, and give you a defensive buff with a short duration and long cooldown!

"
I know this little fiction is ridiculous and hardly likely to ever happen unless someone is trying to troll groups, but the fact that it's even possible is frightening.
