Since Urumi gold cost was not re-worked like other UU, it makes sense to give +1 pierce armour and make the base armour +1/+1. However this unit has to be modified to address weakness to Knights like Shotels are now.
If “Strike Corps” replaces Medical corps, then it is possible to have Gambersons champions as raiders.
If woots steel were a CASTLE AGE bonus, then there would be little need for a better raiding unit than “light cav”.
If they keep fiddling with the idea of slowness of this civ which makes it impossible to counter-raid opponent. It makes sense to have some special civ bonus building like “Temple” based on “Bakthi movement” of medieval age. This should be like a min-town center at half the cost which can produce monks as well as produce, garrison Villagers and drop off resources. But not shoot arrows.
