I am sure as many of you know WoH > Glimmer by simply healing far more for far less. Nothing can beat the healing power of WoH. As a result Glimmer just doesn't compete in its current state...It is a very one dimensional skill and needs a mechanical advantage to offer some sort of alternative to WoH.
Here is a thread I started to list possible enhancements/buffs. Post yours here or there too!

Glimmer is fine for PvP. It is useless for PvE because the quick casting time isn't as huge of an advantage. It doesn't need touching.

I like Glimmer as is, though your fifth suggestion is.....alluring.

channeling + HA + glimmer = good (if you dont entirely suck at positioning)
