Riot, can you rework or buff Alistar's passive?
It actually feels completely worthless right now.
Lower stacks, increase heal. It'll probably STILL be too weak. In fact, it will feel too weak until its too strong, most likely.
His passive should probably be reworked again. Instead of a heal, have it grant 10% MS, 10% AS, +15 bonus armor/MR, or any other stat that would be helpful, thematic, but not overbearing.
Something you can time trades around would make the anticipation for 7 stacks actually feel worthwhile, and would actually scale into the game as well.
