Yeah, they recently changed this about 14 months ago (October 2018)
Is it me or did they recently changed juggernaut so that he cant be stunned when unstoppable?
I've been able to stun unstoppable juggernaut the entire time I've played this game until this month. You are not alone.
You can still do it.
When will the Juggernaut be changed? one of the most powerful characters, and such a non-playable in the game
