Ardent Censer Discussion (and Suggestion)
I like having an enchanter item, but Ardent Censer does need some kind of thought process added to it, so:
(Just the unique element:)
Ardent Censer: UNIQUE Active: Enchant the target allied champion, cannot cast on self, granting it 5-40% bonus attack speed, 5-40 health on-hit, and 5-40 bonus magic damage on-hit for the next 6 seconds (10 seconds cooldown). Your shields or heals against the target while the enchantment is still in effect refreshes the duration one time.
[Cast Range: 1000 units]
This change does open up the item to anyone, but most effective for the shielders and healers. So the buff can now only be used on ONE target at a time with a downtime, or you can perma-buff someone if you have a shield or heal by wait a few seconds and then refreshing the buff duration with a shield or heal (one time per buff cast) which allows enough time for the cooldown to come back.
At the end of the day, the item's power may be the same, but there is at least some kind of thought process required so you have to think of who you want to buff rather than buff everyone. Plus it opens the item to other supports, while still being best bought on shield and heal champions.
Final balance point is adjust the enchantment's power to be less potent if you rush it, but still great in the late game. Example value is changing the power from 20-35 to 5-40 based on level.
