Obviously all of us magic players would love spellcrafting to be implemented. But that's not looking very hopeful.
There definitely needs to be more though. With most of the game's magic locked away behind classes there's very little variety or options for magic players. Especially wardens who only have 4 class magic damage abilities. In the rest of the game there's 4 in destruction staff, 2 mage's guild, 1 psijic, and if you're that way inclined, another 1 or 2 in vamp depending on morph choice.
In the single player games, the main and in some titles only kind of magic damage is elemental and belongs to the destruction school. We already have destruction staves. But they could expand the selection of destruction staves.
Designate the current destruction staves as general / mixed. It has a bit of everything. Then create 3 or 4 more staves, 1 of which would have both magicka and stamina morphs.
1) Melee 1
Many players would love a melee staff. With both stamina and magicka morphs it could offer something to everyone. The stamina morphs would be purely physical attacks with the staff. The magicka ones would be very close range magic attacks.
2) Melee 2
This time a pure magic staff and again with a few close range magic attacks but also several dedicated tanking abilities which would make this weapon the magicka equivalent of 1 hand + shield. The perk option to turn the current ice staff into a tanking weapon could then be retired.
And 1 or 2 ranged magic damage staves. Maybe 1 pure magic damage abilities and the other mostly damage, but also a few defensive abilities.
