Honestly it doesn't matter where the spiney goes but it's harder to get it off a healer than a tank. If I'm mt and spiney is on me at first that just tells me my ot sucks and I need to pull the slack for my ot. As far as melee in that situation they can either dodge ww or they can stay back and used a range atk or wait till after the 2nd ww to come in and finish off supra. The main thing is that spiney is moved and stats after target person gets 2 stacks.
