Is there some unspoken rule to not use Esuna/Leech?

Look at me , im a bad healer, because im too lazy to esuna stupid debuffs in casual content, just to finish the run 1 minute faster

Yes, yes you are. Sorry to say it, but it's kind of our job to heal people and if you're not doing that much you're not doing your job. Doesn't matter how trivial the content, ignorance breeds contempt and just leaves a sour taste in everyone's mouth.

My problem are with people who can't be bothered to dodge Status aoe, since it means I'm screwing up DPS rotation, and more than likely coming out of Cleric Stance to deal with them. If they repeatedly get hit, Leeches will be put on low prio until at least Dots are up.

Neither leeches nor Esuna are adversely affected by Cleric Stance, so I find it's rarely a problem to simply cast if regardless of which stance I'm in. If they're taking damage, that's a different matter, but status effects are plane sailing.

Nah, actually a healers job is to keep the group alive, everything else is called different play styles, it doesnt matter how much i esuna or heal, as long as it leads to sucess.
Its pretty short minded, in my opinion, to call people bad, just because they dont contribute to making your run faster.

Either way, assuming the battle isn't too hectic, why not just speak up as soon as you see this happen the first time? "Hey, just a heads up, you can dispell X! Keep an eye out for it!"
It's better than saying nothing and if they listen, you've just helped them improve and insured a better experience for their future party members. #grouphug

OP is most likely talking about casual debuffs like paralyzis and slow.. and if you tell someone "Hey, you can dispell Paralyzis you know?" he going to be pissed 90% of time lol.

The problem here is that it's rarely just status. At the very least, you're in a position to take a sizable amount of damage when you get hit by it. The is especially true if there is more than one status condition/stacked status.

Most skills which inflict a status effect are low damage hits. The few that aren't are heavily telegraphed and are intended to be avoided, stunned or silenced. Obviously, you play things by ear and adjust your tactics to the situation. Heals should always take first priority, but I'm not dropping Cleric's just for a weak poison or paralysis if the tank doesn't actually need any heals.

A Pacified tank (WAR) cannot grab adds, nor can they tank swap for mechanics that necessitate it. I'll give you one guess as to who those adds are going to make a run for though while your warriors are asking for that esuna/leeches.

Sorry, but if you're ever in that situation then the Tank has already messed up. Firstly by not timing their berserk better, and secondly by not using Flash.

Besides which, if your team is weak enough to be wiped in 5 seconds of aggro you have far greater problems than pacify.
