Deployment Tactics is a raid skill?

[Parawill]

Deployment Tactics is a tactical skill that is much like Cure III. It has its uses and it's pretty good, but there aren't an abundance of situations that require you to go "I need DT over Succor" each time.

If you gauge a situation where you can use DT over Succor, then you use DT. If you gauge a situation where you can use C3 over 2x Medica (potency vs. range)*, then you use C3. It's simple as that. And you don't need to test what ami said. You just simply replace all situations that required Succor, Sacred Soil, Stoneskin, Virus, Fey Convenant and whatever else stacking mitigation you had and throw in DT. :/

*C3 over Medica x2 meaning people aren't stacked or are too slow for C3 to hit them all which in results in either multiple single target heals, healer partner covering those who were missed with C3 or you're safeguarding with overhealing (slightly) by making up positionals for a large AoE-radius heal.
