Nostalrius Begins - Quality wow vanilla realm (1.12)

Hello. I`m new here. I want to play here on classic world of warcraft, the best expansion in my opinion, but I have some questions. If I get true and objective I will decide If I can play here.
1. How many people are playing here? I want to know true answer, because on site is says: 6k people, but I don`t know if it is true, I can`t find it.
2. Why isn`t there armory?
3. What are server rates? I mean exp, gold rate, drop rate, honor rate, proffession rate and more.
4. Are there any items to buy by paying real money?
5. Better start in horde or ally? Where is easier?
6. Are there many twinks? I mean on 19/29/39/49 or 59 lvls? And what lvl twinks are the highest number?
7. Are there bgs all the time? I mean if I should wait for bgs or they are instant?
THANKS FOR HELP GUYS AND SORRY FOR BAD ENGLISH.
