First off, whether you get noticed or not during progression isn't metters paddling, it's a massive scumbag move towards your raid if it is a dps loss on relevant targets.
Second, if too many do that, that kills your raid, as those blow up sooner or later, so having too many people doing that will literally wipe you.
Even if you are on farm, as killing those adds literally does nothing.
Been that way since forever.
And i main Ele since BC, so i (sadly) have firsthand experience on that, you can't beat halfway competent people most of the time as Ele.
