I was playing Dominion and noticed that when my minions started attacking a point (and slowly capturing it) that a little icon started flashing above them. I took a screenshot of it.
I'm guessing it's to alert me that they are making progress, but I'm not totally sure what the symbol means.
Recently all of the status effects in League of Legends were standardized, specifically, Stuns, Fears, Blinds, Silences, and Taunts. What you are seeing is the Taunted debuff.
The way points work in Dominion, is that they taunt nearby enemy minions to attack them (and in the process, capture the point).
