The new charged actions

So I know it's only a matter of time, so let's get it out of the way. What abilities should become charged actions in the future? Maybe as early as 5.1. But yeah with the way these new charged skills work I'm sure most people are noticing that there are certain, non-gamebreaking skills, that could benefit from this.

My choice for right now is Indomitability. Just 2 charges, but it could help is big heals are needed quickly. The alternative is Emergency Tactics, but you'd still rely on mana and right now Aetherflow is a more expendable resource.

On a side note: Please give SCH back an Aetherflow attack skill. MP management is a nightmare now. There's gotta be another PvP skill they can recycle into a "new" SCH skill.

But back on target. Charged Skill, which skills should become ones?

Abyssal Drain, for two reasons.

1.) It would be a good compromise between what we have now and what it was before with the skill when it was on the GCD. The second charge could be kept for healing purposes in big pulls and could do quite a bit of instant healing in said times with both going off near at once. The problem would be with bosses since unlike Plunge it would essentially be a dps gain with no thought of whether you would want to save it, compared to Plunge which you might want to save for knockbacks/getting back after moving out of AoEs and the like.

2.) The skill seems to be considered one of DRK's "core" skills with the way SE uses it, atleast animation wise. Used prominently in the lvl 70 quest for Fray's entrance and was also the skill scene change for DRK in the SHB job showcase.
