I've just ventured into Shattrath city for the first time, and I must admit I am feeling a little bit lost.
- I spoke to a person with a quest exclamation mark above his head and became neutral with the Lower City. Is this just like an Orgrimmar faction? Or does it have any special meaning?
- I later asked directions from a guard and became neutral with The Sha'tar. Is this faction anything special?
- I know there are the Alvor vs Scryer factions, and I could see the two sections when I opened my map. But I went into a bank in the terrace of light (middle area) and noticed the banker had "Aldor: Quartermaster" underneith his name, should I not talk to him before I choose my faction?
- I spoke to another banker that didn't have either Aldor or Scryer under his name and became neutral with The Aldor, are they anything special?
The only thing I HAVE learned so far is to not jump down from ANYWHERE as you are usually higher up than what your hitpoints will allow for.

Any help will so be appreciated...
