Heres a strat to get over those toxic players who taunt you every single time.
Ignore them.
They have tricked you into falling into their trap.
if you get mad your goal changes and you only focus on getting them for revenge just continue playing.
dancing when you kill someone is a quest/mission so they just happen to have it.
someone on this wiki told me about it and i really appreciate them for it because i used to get so mad when someone taunted on me.
And when you finaly get them the next time they vanquish you they dont dance. That means they completed the mission/quest
