NA player interested in Frostwolf realm

NA player interested but have questions
I'm from USA (NA) and I am thinking of playing MOP expansion: what are the pros and cons?

Additional questions:
1. How long does it take to reach level 90?
2. What is estimated wait times for bgs/arenas? Is there solo que 3v3?
3. What's the ping latency for USA players? How strong is the population for NA times?
4. What classes are the most playable without many bugs? How is monk or hunter classes?
5. Anything else I should know about this MOP realm?
6. How long is the grind to full pvp gear? Are there rating restrictions on items/weapons?

Thanks!

1. It only takes a week or so to lvl to 90
2. Wait time (Alliance) no longer then 5 mins most are instant
3. Ping is good. Server is **** sometimes
4. All classes are playable but the questing is what's broken.
5. its MOP...no a huge player base
6. yes there are restrictions on weapons (need X amount of honor/conquest each season) and there is 2200 gear. To get fully geared its quick if I you can get someone to carry you in 2s. They have that back log of conquest points so when you ding 90 you get an instant 10k+ arena cap.
