Unfortunately, your attacks while mounted are limited to weapons; if you want to cast spells, you still need to dismount
Does that mean that we wont be able to use Mystic bow in mounting combat? Thats rather frustrating!
As well as spells that affect the mount (for example, make it temporarily faster, coat it with a frost aura, and so on)
