Well that was slightly off topic but I'll add my reply. I somewhat agree, but I don't think it should be limiting it that much. It also sounds that your view is incredibly good V evil. I have seen goodhearted orcs, and there are also many evil humans, elves, and dwarves.
I think races like Yanar, Maiar, and Agni are part of what makes massivecraft unique. I think that adding diolek, tokaige, frostmorn, and all the others ones might be a stretch, but as long as they don't add any more races after that, I am fine with it.
Also the skin thing is a different problem. I myself found a skin that looked a lot like a Yanar according to massivecraft lore, and nobody I have roleplayed has had any trouble guessing my race. If you need a decent skin for massivecraft, there is a skin thread in the media forum where you can request a skin artist to make a custom skin for you.
