Malzahar Voidling Request

Small request, now that the Voidlings are an ability could they maybe not die when Malz dies? The ability is nice and all but on modes like ascension, where you die frequently, it looses a lot of effect. Maybe to balance them out they either a) can't spawn any more when Malz dies or b) they spawn from malz but maybe at a reduced range. Option b would make it where if Malz dies with a Voidling out, the enemy has only to move away from him and they don't have to worry about any new Voidlings. Just a thought. Feedback as to why not would be appreciated.
