Hammer 5, ring of warding in WvW
It is either stability or timing. If you time jumps correctly you can jump right over wards. Also since mesmers can now provide group stability it wouldn’t surprise me if they knew you pop the mantra the second they saw a hammer guardian.
If it doesnt have Stability, it has teleports.
