Why are there so many complaints about this? I get the big heal that it gives as well as applying damage, but isn't there suppose to be two supports in a game? Shouldn't your team have a support that more than likely is carrying this item?
What am I missing here?
Just because both teams have one doesn't make it balanced.
If it's built by both teams, every game, with little consideration for other items, it's probably overtuned.
It's broken along with the broken locket shield
The complaining parties probably had a 
supp who decided full AP was the better choice (for himself)
I personally like 
, I feel like I make as much of a difference in the game as a mid lane mage now, not just some bot laner, who becomes a sightstone when lane phase is over. The only thing I don't really like about redemption is the range on it, too strong of an effect to be semi-global range.
Like if someone has solid vision of the map and they want to go in for a 1 v 1, it feels bad having a support butt in from 3 screens away
