Is there a way to actually use Plenary Indulgence?

[Silver-Strider]

The ability is underwhelming.

At worst, it's an AoE Regen tick
At best, it's an AoE Cure 1

There are just a few key problems with the skill.

Firstly, is the cost associated with using the skill. Getting confessions requires that a person be healed by our AoE heals which isn't usually a problem unless in 8 man and your Cohealer is obsessed at keeping everyone at 100%. However, considering the general cost of our AoE heals (in particular Cure 3 and Medica 2) it can be costly if those skills are made ineffectively because of overhealing. Even when accounting for Thin Air, it's still an investment and PI doesn't feel like much of a return on that investment, especially when compared to Assize which does a similar function + extra for no real investment at all.

Secondly, the skill's duration is very low for the arguably small heal. 10 seconds is hardly enough time to make great use of the skill and while it's possible to extend that with more AoE heals, a large majority of content does not require that quantity of healing, greatly limiting the viable usage of the skill. The small duration of the skill also leads into the 3rd problem of the skill and that's the CD on it. 60 seconds isn't a terribly long time but on a skill that is often times used at 1-2 stacks, outside of raids, the weak heal feels even more underwhelming knowing it's gated by it.

I use the skill in practically every instance I can but no matter what, it doesn't feel like it's made much of an impact on a player's health unless it crits with 2-3 stacks on it and even then, it ends up being an overheal in most cases.

No matter what I'm doing or when I use it, I've never really been impressed by the outcome of the skill at all.

Just some slight adjustments off the top of my head.

Slightly increase the potency by 50-100 points per confessions.
It would still be weaker than its original potency but at least the heal would be better considering the investment.

Extend duration of confessions to 15-20 seconds.
The rigid 10 second duration offers very little flexibility with this skill that it's either use it instantly or not have it available for use later. An extra few seconds won't break this skill at all.

Reduce the CD to 45 seconds.
Again, an arguably weak heal on a 60 second cooldown seems excessive, especially in comparison to Assize that benefits both from Lilies as well as the Secret of the Lilies 2 passive to further reduce its cooldown.

Any 1 or even a combination of the 3 would be a great step to making this ability really shine more.
