Adding to this, I just got the same bug in my match: 35292048
It was also the movement buff on just one side of the map. afaik I was the only one seeing it. I didn't see the other team try to hit it and I asked my party if they saw it and they said they could not.
I think balancing around multiple playstyles is definitely the right choice and I love the idea of a holiday hitting a standoff "fan the hammer" against another player/team.
Love this idea! I was just thinking about how I miss multi unit heroes from Dota. My fav character was Chen in Dota. I would love to get an army of some sort built up, sounds so fun.
