The mechanic is the source of many complaints.
Quest bugs would not hit half as hard if you could just go on and come back later after it is fixed.
While you are at it, make VR mobs give more than an minuscule amount of xp, because at VR every quest bug blocks progression.
You could surely silence a lot of complaints.
I would love to hear the reasoning for the gating through quests, because i just dont comprehend why it was done.
