New gem - Consecration Support

I'm wondering what are your feedback on a support gem that allows a non-instantaneous-, area of effect skills to generate the Consecrated Ground-effect.

Personally I would likely use it with Frost Shield, as a means of healing up my minions outside of combat as I don't have enough skill slots remaining to fit in Convocation (And I'm also a bit pressed for sockets - Though I can spare one for a support gem tied to certain skills).

I won't benefit from the healing effect myself, as I'm using an armor that gives me Zealot's Oath, and since the critical strike chance bonus only applies against enemies within the consecrated ground, it won't offer a damage boost.
It would be kind of like the Holy Flame Totem, but on a cooldown and always centered on my position during casting.

Zealotry, Purifying Flame, and a Bottled Faith do this.

Add a chance for a skill to create Consecrated Ground is interesting, and as a basic concept I would agree - hell, EVERYONE would.
You need to give more examples so that we can actually argue how to better implement it.

For example, something like:

---

Consecrate Support
STR-INT
Support any skill that hits enemies. Supported Skills creates Consecrated Ground around you (the caster/proxy) and any enemies hit by the skill. When supporting a Minion skill, minions created by supported skill cannot create Consecrated Ground this way.

Normal quality: Consecrated Ground from supported Skills has +1% Increased Area of Effect
Divergent quality: Enemies on Consecrated Ground created by Supported Skill has +1% Chance to Receive a Critical Damage
Anomalous quality: +0,1% Max Life Recovered per Second from Consecrated Ground created by Supported Skills
Phantasmal Quality: +0,1% Max Mana recoverd per Second from Consecrated Ground created by Supported Skills

Supported Skill creates Consecrated Ground around any enemy hit and around you
Consecrated Ground base radius is 5 (hidden)
Consecrated Ground from Supported Skill has +(0-90%) Increased Area of Effect
Consecrated Ground from Supported Skill has (+0-19%) Increased effect

Not a bad idea. Gifts from above casts a 'consecrate' spell already, so should be pretty easy to make this into a support or active gem.

As an alternative you can have purifying flame on a trigger weapon or cwdt to create it. (or run zealotry if you're crit)
