Ok, let me speak from my personal experience then. I used to play Heralds and only Heralds. I loved playing Heralds, but when some big bad person came to the Inn... well, I was toast. Did it make me a better role player in the end? Sure, I think I do just fine. That being said, after playing only Heralds for so long, I was significantly lacking in player killing skills. When I finally decided to try out different cabals, I looked like I was a total newb again. I think if you want to play a herald for your first character, go for it. It will most likely be a really great experience for you, but I will urge you not to continue playing consecutive Heralds. This is a player killing and role playing mud, and to take in the whole experience of what Carrion Fields is try something else for your next character. You will at least have a wonderful basis for your next character by being a Herald. Oh, and identify everything.

Good Luck!
