New Zilean Passive
The new Zilean passive is a unique passive that allows him to level his allies as well as himself. After playing a few games with him i always wondered what use is his ult when everyone is level 18. This is where i suggest the idea of allowing him to over level champs kinda like how you were able to in URF mode. IDK if anyone has suggested this before, but i do think it is something worth thinking about.
