Redemption

Is it just me that haven't learned to play around the item yet or am I wrong to think that the item might seem a little strong for a support item compared to the fairly low cost it has? Not only does it have insanely long range it also has quite a big area coverage for the AOE effect. I know it has a 2.5 sec delay but given the area it cover I find it hard to be able to get out even at high movement speed. It is basically 10% max health unavoidable damage, not counting in the friendly unit heal it also provide, and it only cost 2100 to build.
