I think I understand why they adding reskins as new armors. Ubisoft is focusing on servers, balance etc at the moment. "If" there is a plan for Year 2 I guess they will work more on "new" new armors. If dedicated servers will be git gud they will only have balance, new heroes and armors as priority target. What are you guys thinking? Year 2 or For Dead?
They have also made clear that new armour is harder and more time consuming than new weapons because the armour actually has to move properly with the characters, sure they could have rushed a few sets out but people would soon complain of it being disjointed or clipping.
They have new armour sets coming in season 4 so we should certainly be seeing a few newly decked out heroes then.
