Realm Bosses currently have very high bonuses to resilience and hit chance. My understanding is that its not possible to critically hit them, nor to dodge them. There has been some discussion on changing this, and if its changed, we'll let you know in the patch notes.
Thanks for letting us know
Its nice when someone from Tynon share info and gets involved so we know where we stand
Big compliment,thumbs up for getting involved
