Garen no longer moves during spin and there's nothing about it in patch notes.
Garen no longer moves during spin and there's nothing about it in patch notes. He used to move during spin if his target unit moved, or if he killed a unit he was targeting and pathed to his next targeted unit. If the spin stops he starts moving again.
Also show a unit's attack range on the map when they're hovered please instead of only showing 1-3 in the interface.
