What is the Downside of Archery/ MA?

[Hodo]

but all the archer has to do is turn right? or god forbid, archer stays on your right side and just follows your turns, its not like mage where he cant turn while aiming and hes at the same speed as while attacking so you cant escape and you cant follow unless you are range. archer needs a speed slow the moment they pull the bow back

Dont get me wrong mounted magic needs help. That double casting time at max skill is completely un-needed. As for the turning thing, in many ways two mounted archers or more for that matter it turns into a beautifully chaotic two dimensional dogfight. People turning and jockeying for position to do as much damage as possible while minimizing what they are taking.
