Just another point of how useless this things are. I know they are supposed to die when affected by hard CC (stun, knockback etc), or randomly with no reason at all (lol). Just did multiple tests in Guild Hall, me on scrapper, my friend on a guardian. After I down him, I stand on his body, cast functionless gyro on him and use Defense Field to give myself and all the allies around stability.
Gyro gets destroyed when my friend uses down 2 skill, despite the Stability.
