When playing Alistair in ARAM, his skill description for his E says that it would heal his allies for half of the amount that the skill would total up to, but it would only ever heal 1/4 of the (normal heal amount + ap bonus) total. I don't know if using the Infernal skin had anything to do with it but that's what I had done.
El Condor Pasa1 votesDebuff on the Howling Abyss halves the effectiveness of healing on allies. Alistar heals allies for half the amount he heals himself. 1/2 of 1/2 is 1/4.
zzman730511 voteson ARAM heals were too oppressive, i cant remember what patch they really hit them but somewhere, ( i think 5.1 ish?) they made it so self heals are reduced my 20% and heals on ally's are reduced by 50%
El Condor Pasa1 votesSelf-healing is not reduced.

Self healing is back to full strength on ARAM, but all healing effects on allies are reduced by 50%.
