Guild Wars 2

Mesmer staff 2, phase retreat, sometimes stuck character to the ground after use.
I?double checked so it was due to knock back, stun , imbolized or any cc effect, it appears to be a bug.

Phase retreat is neither a condition remover (immobilized) nor a stunbreaker (knock down/ launch).

The actual bug is that your character stands up and the global cooldown (knockdown CD) is reset.

Also happened to me last night in EBG. Used staff Phase retreat and was stuck in place. Waypointing fixed it.
