Maybe RDM need....

[cactuarzzzz]

It is only a cure 1. And what you outlined just there is why vercure doesn't need to be included in your suggestion of things that get turned off for a DPS stance. Vercure is RDM's only answer to second wind/bloodbath etc; it has no cooldown, but in exchange for that using it is a dps loss except when the boss is not around to be targeted, in which case it becomes a DPS gain allowing the Red Mage to prep a dualcast for when the boss returns to the field.

And why do you need vercure when

in ES1 you have melee who can take prey debuff from you

in ES2 no melee who got second wind/bloodbath need to use it if healer is competent.

You said vercure is just a cure 1 and imply it's insignificant but then you kinda contradicted yourself by saying if you can't use this weak heal in raid it is a big deal.
