That would be a little OP dont you think?
The game is already OP.
Enchantments that make magic completely free.
Smithing can make you a God of battle.
But no I don't think it would be that OP. It would just be common sense.
You hold a bow in your left hand and use the right trigger/mouse whatever to attack with it. So you would have the spell visually in your right hand since the bow is in your left. So would you reverse the controls?
Eh, Oblivion was MUCH more friendly with anything/magic hybrid classes, since you never needed to unequip your weapon to equip magic.
Well I don't know about Xbox controls, but for PC I think it would just be.
Bow in Left hand. Left MB to draw the bow, and while the bow is drawn. Right MB to zoom in.
Spell in right hand. Right MB to cast spell.
