We will probably remove the fear resistance from banner carriers in the next version. However, we still want fear resistance to be more easily available than in the previous version, because there has to be some counter to Mordor chain-fearing an army with several Nazgûl or Gondor stunning you with Boromir's horn and then dropping an army of the dead on you. Some ideas I found interesting were giving fearless leaderships to Mordor drummer trolls or Rohan Captains, so that it's more limited and expensive, but still available if you really need it. It could then be countered in turn by taking those units out.
