Redemption should not be in ARAM
It is already very cost efficient and "broken" to be considered healthy as is, but in ARAM, it is much worse. The stats, while not combative (no ad or ap) are really good for combat when healing is not available by backing. Also, the whole healing/hurting active is pretty strong since the diameter is more or less 70-80% of the lane's width depending on where it is used. AND that it can be used when dead is huge. If anything, this has made lopsided games where one team has a healing champion (like Soraka, Taric, Kayle, Nid, and god damn broken SONA) far better for the team with them and worse for the team without.
and
can be a decent starting items for a Soraka to have in ARAM.
