Faking kicks isn’t as important as it might seem, it can often be better to just get kicked when you aren’t really doing much then leverage the temporary kick immunity to get off a void torrent or mfi’s. Not to mention getting kicked to cast flash heal safely for the 10% Dr can also be a life saver.
