While Ethereal Shift is horrible choice, Metal Skin purely depends on hero you are playing, like I play MnK so I just burrow, wait few seconds in Haze's ult while circling her, turn on Metal Skin, unburrow and ult her, works everytime and she can't do anything excepting cancelling ult and trying to run away early but my circling makes it hard for her to aim dagger at me. For many other heroes it's just enough to dash out safely if they don't have CC.
Read my post, he gets 156% dps due to his own dumbness, ofc he gets vaporized when Lucky Shot procs on that for like 290% dmg combined.
Return fire returns 60% based on raw dmg that you were supposed to receive before reductions.
Her ult is only bugged when one target dies and 2nd still lives, in both cases in vid he died alone.
