In its current state, Deployment Tactics doesn’t serve much of a purpose in the game. The skill is either underwhelmingly weak for a 120s cooldown, or overwhelmingly finicky that using it is just not an option in most scenarios.
Let me give some examples:
You need a partywide shield, so you decide to cast Adloquium on the Main Tank and deploy the shield instead of casting Succor.
You have saved 100mp and gained shield strength of up to 150p, at the cost of a weave slot and 180p worth of health healing.
So an overall loss of 30p healing and 80p of damage from the weave, with a chance of losing further shielding if the target takes damage before you can spread the shield.
So spreading an Adlo outside of prepull isn’t really a viable tactic. Let’s check the other galvanise that you could spread.
There are multiple AoEs coming out in quick succession. You cast a Succor beforehand for the first one, and want to spread your shield to cover the second one. Since everybody will be taking damage, you will either need a PLD/GNB to use their invulnerability skill, or precisely time your Deployment Tactics so that the old effect is broken before the new one applies, but the effect is still there for you to spread it from.
Not an easy thing to do whatsoever, so it can hardly be relied upon for standard mitigation.
Best case scenario, you gain 225p shielding for 80p from the weave. Worst case; you gain nothing.
TL;DR Deployment is a 30p or unreliable 225p gain for a 120s cooldown.
Hardly worth having, let alone being classified as a signature skill comparable to Holy and Fell Cleave. So what should we do about it?
First - decrease the cooldown.
Other GCD-affecting oGCDs (Horoscope, Plenary) have a 60s cooldown for a 200-400+ healing gain. Homogenisation is bad, but we’re standardising, not homogenising.
Second - Give it a more accessible effect.
Have it restore broken shields in the area of effect to full health, and spreading the full health shield. This means that galvanise effects would persist when broken (probably have a cracked and greyed out icon)
Finally Third - Give it an effect outside of Galvanise.
Plenary can be used with Afflatus Rapture, Horoscope heals uncharged. We shouldn’t have to give up a damage GCD to use Deployment. This is easy enough - have it affect Seraphic Veil.
So now we have a 60s oGCD that can shield for 225 potency if you need to cast a Succor, 210 potency for a 3rd mini-consolation effect, or 435 in the rare case that both are required. The original usage still remains, of course, and is now not prone to being damaged before spreading.
