Heal Change: Ether Renewal
That would make is a little overpowered IMO. This is want Anet should get away from. They should in general with every heal is lower the base heal and raise the ratio from healing power.

Having it as a cast time then an after-effect would make the heal a lot better because I absolutely hate it when I get interrupted right when I start casting ER and it just goes onto full cooldown without any kind of heal.
It’s a great utility, but with high opportunity cost. You get easily interrupted if not properly positionned/timed/covered, and you can’t apply any pressure except insta cast abilities. Armor of earth isn’t even a guaranteed full channel due to boon strip/conversion and it’s a huge waste anyway. Under heavy pressure and focus, you can just forget about it unless you can LF to a safe spot.
It would be nice to have on heal skill procs from runes start at the beginning of the channeling though. It works with rune of radiance (light aura at start of the cast), but most runes apply the bonus at the end. Rune of the revenant could work the same way for instance.
