Cleansing Synergy trait and Medic Gyro.
I am almost sure it does. I’ve been using Medic Gyro in pvp and wvw for a few weeks now, and I noticed a condition being cleansed when using Medic Gyro.
Also, yes, Medic Gyro is a solid alternative to Healing Turret. It is instant (that’s why you’re almost forced to play it in WvW roaming), the toolbelt skill is amazing, and with Rune of Water (that I use mainly for the boon duration), it is also a decent burst heal. Not to mention that traited with Final Salvo and Rapid Regeneration, you get a lot more healing than you think.
