Well, guess I'm necroing this. However, I feel this needs to be said.
There is one thing in particular that has been irking me about what I've seen about your RP is the following; Death Knight relationships. Death Knights, and I'm sure you've heard this before, have slaughtered their friends, or just complete innocents, against their will. Now, I would normally say that one is enough for anybody, and leave it at that. However, from my limited knowledge, you seem to be pioneering dead-living relationships, what with 2 of them. I then took it upon myself to do this.
Of course, I can't give you any real life examples to tell you what being a Death Knight would be like, nor can I make you go kill your best friend so you would know what it's like. However, I can direct you to
multiple resources that (Not sure about the validity of that last one, but it had DK in the name) possibly can help you refine your roleplay and perhaps even the RP of those around you.
I apologize if I offended you in any way or manner during this post. I am not posting in this thread again.
EDIT: Also, if you would like a more rapidfire Q&A then could be achieved via PMs, then I can help you in-game. Just call me.
