I hope Mesanna someday let reds go to all facets. They can't do anything a blue can't do so it would not hurt anything. It would however remove a lot old stories about reds, when reds and blue hang out together. Before you know, you will forget about the colors and look at the player instead.
This old hate to reds do not exist on Siege, there we look at actions instead of colors.
How do you know if the char you use to hang out with do have a red in Fel?
I remember long ago on Atlantic Year 1998, I was hunting with my blue and joined up with 2 other blue. We had a great evening and enjoyed being together. Then we got to speak about reds and was very surprised to find out, we all had a red too.
It would really be healty for the community on Prodo shards to get over this old scary fear for reds. As long you stay out of Fel, there color would not matter at all.
