ZOS will help melee magicka characters a lot if they add a passive in soul magic skill line which sclaes to your highest resources.
Soul imbue : imbue your weapons with soul power to make them scale with your highest resources. Damage done will scale with either spell damage or weapon damage depending on what is higher.
Heavy attacks will now return resources based on your highest resources pool instead of either magicka or stamina.
This would help magicka melee builds a lot and add flavour and merits to playing at melee range instead of being forced into playing melee cos most of your attacks can be dodged.
