I've tested this in the aerodrome. Allies affected by bulwark gyro aren't redirecting damage to me. In open world, I'm not seeing any redirected damage in the combat log.
Has anyone else managed to see this skill actually working?
You cant test it in aerodrome. Arena damage doesn't work on bulwark. Pretty sure almost all relevant boss mechanics dont trigger it. Scrapper is just useless in pve. Just go core if you want to play healing engi. Or even better, dont play engi in pve. This includes holo.
Well. I've gone and tested this in the PvP lobby (with people getting hit by the dummy foes) and in open world. In either case, people getting hit by attacks with the bulwark gyro buff are not having any damage redirected.
So this skill just flat-out doesn't do the thing it's supposed to do.
Try it in WvW when your Zerg gets attacked.
