Guild Wars 2

Quickening Zephyr prevents healing while active. You still get the DoT heal as that comes from the aoe field the spring creates. If you use other healing skills such as Heal As One while quickening zephyr is active you will not receive any heal at all.

Thought it was a bug with quickness in general but tested with QZ and Pet Swap and it was just like you said! Thanks

Completely normal, the skill is preventing heals :
