This is not the same thing, at all, fyi.
Cleric Stance swaps your INT and MND stats while boosting attack spell potency by 10% and decreasing healing spell potency by 20%; every healer has access to this skill. Stacking INT as a healer is strictly bad. You get literally no benefit from it outside of... dpsing out of Cleric Stance or healing while in Cleric Stance. But we call either of those "Playing the class wrong" and don't use that as a metric by which to measure players.
Also, it really depends what content you're running. Keep in mind that if your health is too low to survive the biggest hit in the encounter with proper mitigation, you SHOULD put more Vitality on. You just wanna ride it as close as possible (accounting for RNG; don't survive it by 100 hp, survive it by 1000) and turn the rest of the VIT into STR. Assuming you want to maximize the class you're playing, of course. If you're looking for safe clears and don't trust your healers, by all means be a fluffy lovable tank who shrugs off unmitigated Flattens.
