The thing is though, unlike yourself it seems, people do make mistakes. I'm sure it's great that over the last two or three years you've never had someone die while being in the stance dealing the upmost damage.
Though that is an unlikely scenario for a majority of the players. Last night I was trying to finish off getting a drop from Alexander, the AST decided to start DD'ing Faust right off the bat and died. Now in that scenario, multiple actions didn't happen that could have prevented such a death, yet it happened. This may refer back to your statement "unless you're terrible..." which comes back to, yes some people have terrible moments or habits. That's a staple that cannot be changed, with the exception of yourself that seems to have been blessed with skilled players much like yourself. Which is wonderful! No sarcasm, if you've had an easy time where others (including myself, being on the terrible list) have struggled then that's amazing.
There has been a few discussions on Cleric going away, though if it were to go away do you think the bad that will come from that will outweigh the positive? If you do not see a bad side to it, then I guess that answers my question right there.
Still, a lot of others have said that they can go through a run with Cleric on. That is true, so to those people hitting that button is just pointless. Yet, remember..we get nothing without giving something up. Are you willing to have reduced potency? higher MP consumption resulting in less casts? Shorter DOT duration? Mind you all of these do go wit lowering the over all damage, when I say potency I mean the direct spells damage, not overall. If we were to get the stance gone and scale to mind. What would you be willing to receive on the negative side of things?
Me personally, I do not mind if it stays or goes. If it goes I wouldn't mind potency reduced while MND is scaled off of it. On the other hand...
I believe you're correct, that is the way to go. It may make some spells / abilities have a lot of text, but when you run your job you learn to know these things. It could easily make it so you have two skills in one depending on your stance, which could give some flavor to the stance dancing.
