Ok but why?
Rogue a sneaky slow moving methodical sneaky fighter.
A paladin on a horse being slower then this just do not make logical sense.
If you want to go down the route of paladin using the Horse to get around you really need to make it make sense why the paladin is slower then a class that is literally about sneaking around obstacles to not draw attention to itself.
Remember Stealth is not a magic ability it is not invisibility in your own lore.
The idea that the paladin a knight on a horse is slow but a rogue who is in stealth is fast is just bad.
There is a reason why inn vanilla rogue had minus movement speed when in stealth.
I understand it for the games sense but the horse really does not fit when you start to think for a second on it.
Losing utility that we have had literally from day one just feels bad good that it is understood now.
Ret paladin has less utility now in Dragonflight (and no changes to the utility by the way) then it did in Mists of Pandaria.
Overall glad to hear something is being done it is to bad this is the third time we hear anything from blizzard about paladin in Dragonflight from Alpha til today.
