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

[Lillia]

Why even fight the enemies? Let's just let them live in peace and sit around town instead, it's easier that way.

There are actually people who don't care about DPS rating though and just want the dungeon clears... I am also actually at fault of being a little more casual and non-caring when I play in a norm dgn that I know will be cleared eventually as opposed to if I am raiding...

This doesn't mean I'll just leave a debuff on if I can esuna it but I def get a bit more "ehhhh" in runs that bore me a little .-.

Edit:

I've never healed in this game, but if it is anything like WoW healing then I know the issue.

As a healer in WoW I would often be to focused on healing mistakes by dps (standing in fire), raising the dead, and trying to avoid mechanics while not looking at the battle. Seriously as a healer you are constantly looking at peoples health bars instead of the ground under your feet and it can be hard to avoid stuff as a result. While dispelling is important, unless you have an instant kill debuff on you, dispelling your 5% reduced stats or slow effect is at the bottom of my priority list.

Then you also have the healer woes of cleansing those who may get hit by a mech that actually causes these debuffs like.... 20x.. >.<
