Know for myself personally I will not cleanse certain stuffs during 50 and pre-50 pulls of legends. Only exception is disease or accumulating poison stacks and stun. Especially for white mage with it only having one ogcd heal that is best used with tank invuln anyways. That one single gcd at that level I spend on esuna can and does kill people because having nearly all heals tied to the gcd stinks. Oh does it stink. Again for the white mage, that 400 mp per cleanse really begins to add up when only mp regen is from lucid. No thin air until post 50? Really chaffs my everything that does!
If the option is "remove this vuln up" or "stun the pack two more times with holy" I will keep spamming holy, half the time it dies before that debuff even would have been issue.
Would be much of the happier if people interjected Banish III because that causes 90% of wipes during big pulls in that dungeon. No really everyone, Banish III doth not mess around.
Exceptions of course made for Sludge - Burns - Windburns - Dropsy - Freeze because those are big ouch. Obviously Doom gets the Esuna or anything like it.
More healers may Esuna if it were ogcd or we had group Esuna, hate the way that skill works. No clue what is with every mmo and not giving group cleanse. Oh well! At the least it gives weave window on White Mage during pulls...
Other honorable mentions for screw this I am doing deeps are certain slows (some enemies use arms length) because you will keep getting it over and over by hitting the target. Then there is the vuln up in Dismal Darkhold that is instantly re-applied every gcd by the tiny squidy enemies.
