The person you replied to said "I had a 'debate' about this recently with a healer during expert roulette."
As a White Mage, I cannot begin to understand how someone could not be confident with Cleric Stance by the time they reach expert roulette.
How much patience and empathy are we supposed to have for someone who chooses to enter expert roulette with a level 60 when they aren't confident in using a large portion of their skill set.
I can absolutely understand being patient with people in pre-60 things. People are still learning. But in expert roulette?
We need to draw a line somewhere.
But by the time you get to 60 with any job, you should be confident in your abilities, especially abilities you get at level 6 (Conjurer level 6 gets cleric stance)
