So is anyone else getting annoyed with trying to switch targets on healing but then it just auto locking to minions or someone with full health or just not switching targets at all?
Yeah, some of us have talked about it a bit here: Miko's alt fire doesn't always work
Here: Request to have Miko's heal prioritize lowest health target or highlight current heal target
and here: The Challenge of Finding Teammate's Health Bars
Hope it helps!
