Revisiting the physick question

[SilentVoice]

you keep refering to lore when it comes to RDM being a hybrid mage, but reality states that he actually isn't. after all, RDM is a DPS job and there is no way he can replace a healer in any encounter just with his verraise and vercure. if they could have made something like stance switching (b\w DPS and Heal), that changes skillsets before pull and such, then you could've said it is a hybrid. but FF14 isn't designed for hybrids like these, best it can do is somehing like it was for AST (main heal\off heal), not complete role changer
More on the topic, while having Physic INT based on SMN could greatly help practice\certain kill groups, we know our community and emergency healing to save the day may become expected from SMN and could be a trigger to rage.

and there is no way [RDM] can replace a healer in any encounter just with his verraise and vercure.

This is patently false. In most content outside savage content and 24-man, a RDM is more than capable at healing. To the point that if you have a preformed, it's actually a viable strategy to do dungeons as Tank, RDM, DPS DPS. It'll be a lot busier than as a healer, but it's more than possible to do. E.g. I've healed the vault's final boss as a RDM when the newbie WHM fell apart the first two attempts. After they died yet again before the boss's ultimate, I just switched over to main heal and finished up the fight for them. It was full of clutch moments, for sure, but it's definitely doable and there isn't really any other fight that requires as much healing as that one in normal content.

That said, I don't advocate being a RDM that heals on the side to 'help' the healer. If a healer is there let them do their job and focus on what you're there for which is dps. If the healer dies, or your preformed chose to not bring one along then go ahead and heal away.
