Austin is making a good move here. He probably could have worded it differently, but at the end of the day, he is trying to improve things.
Its very easy to explain why a elf lives in Malinor, a Human lives in Oren, and a Dwarf lives in Karik. Its logical to assume the same thing with Orcs in the War Ugz. Now with that said, things do change. However its very unlikely that a server application would allow a whitewash orc. They do (to my knowledge) filter out orc characters that wish to be different (and if they don't they really should consider it).
Therefore when a player makes a whitewash, its usually after the whitelist. This is what Austin is trying to figure out. Did these orc characters start in his nation and then become whitewashes? If this is so, why? Its his job as a nation leader to figure out why someone would leave his nation, not someone personally persay, but why people in general would want to leave. If many are leaving for the same reasons, it gives him a base to work with to make changes as needed.
What the concern is, people just wishing to play with other races. Perhaps they like the culture better. Maybe they have friends there. My advice is to reroll that particular race.
Alot of the time, people roll a character then end up making a new character that is an orc and just chooses arbitrarily to be a whitewash. That is where many of the concerns are. I'm sure Austin would like to know why people are doing this. Why they would wish to play an orc outside orc culture.
He also wants them to make sure that they understand the consequences of their actions. IC actions have IC consequences after all. Unfortunately he is only giving the consequences that comes from other orcs, and neglected to say what other races might do.
I'll speak for the general leadership of Malinor. Whitewashes are quite simply hated more than regular orcs. They are seen as one of two things. Spies from the War Ugz, or a Psychopath.
To the elves, the war is a political endeavor, they do not hate the orcs on a cultural level (even if they say speeches and such that contradict that). They see the whitewashes as exiles from a culture. Psychopaths who resist their own kind and their beliefs. There is only a few reasons they would do this. 1. they are simply crazy which makes them dangerous, 2. they have done something despicable, so vile that the orcs even hate them, such as undead/Iblees worship, and 3. they are fugitives, criminals and traitors to their own kind, we see them as if they would betray their own kind, they have no problem doing so to anyone else.
I'm sure the dwarves would have similar feelings. Hiebe can probably comment more on that if he wishes. Humans are probably a little more accepting, but who knows? They are a religious people and may consider them vile monsters too, but that is up to their leaderships.
Playing a whitewash means playing a general exile. Going to need to more than likely live in the wilds. That is if the nations are playing the game properly too. Perhaps a movement to get them on the ball too will help the issue.
This isn't to harp on or punish the ones playing whitewashes. The lore is there and the lore should be followed. Lore supports there being whitewashes, but it is a hard life, one that the player should consider carefully before engaging into it.
