No one measures healing over time in this game. I main white mage and have done all kinds of challenge heals like solo heal T10, T9, have healed every fight in the game to completion and can't remember a time where anyone even talked about healing over time. The only thing people care about is whether or not I got the MP to keep healing cuz a white mage overhealing = a white mage standing around with no MP to heal anymore.

My monk does 600-620 DPS typically in most fights and that is considered exceptional DPS. As long as you are getting 500 in FCoB no one is going to say much of anything to you cuz 500+ is considered good and can meet all DPS checks just fine.

But if you're getting 400-450 (or less) in 15-20% echo fights with i130 gear you should read a guide and try to fix your rotation because that means something is very wrong with it. I only mention this echo fight parse because I see it happening way too much and it truly is unacceptable in my opinion but I can't really mention people's numbers because it's against ToS so I need to keep them blissfully unaware of their bad rotations >_>
