its a great way too protect a character keeping them inside a unit from missiles and spells and they can mutually benefit from each others abilities/banners/spells items etc and not be jumped from every angle possible , ofc there would be limits in terms of what mount you using and lowest speed would apply too all etc..
particularly in TT where slann were attached too temple guard with no choice, also had mixed kroxigor/skink units so mixed units could in respect to Lore be added to the game giving us more options too play with..
makes sniper/direct sniping spells a stronger specific role too pick them out even in units..
CA please give us Shogun Multi layer wall Sieges back along with Roles/Fog of war we want EPIC sieges!! 'personally i think the 3 kingdoms style of building armies is the best for balance alongside stronger unit roles and larger unit sizes' also allowing Chars too specialise in range/siege in particular in skills/traits..
