I guess it's intentional

Issue: tempest skill flowing strike with Fluid Vestments chest essence. This makes the user invisible and invulnerable in battlegrounds. It makes killing them impossible. Some people are taking advantage of this bug Plz fix asap ty

The Fluid Vestments are supposed to make you untargetable…

If they use the Blur node from the Harbinger paragon the dash also causes invisibility…

The combination of the essence / paragon node would suggest this is exactly the expected behaviour, i.e. invisibility and can’t be targeted. So, what’s the bug?
