New Player, A Few Questions!

I just joined Warmane with the intention of leveling up on Lordaeron and participating in the progression on the server. A little bit about me, I raided in WoW in MoP and stopped after the first tier in WoD due to boredom. I raided at the semi-hardcore level each tier around US 35th, the reason I say that is because if I am passionate about something I put the time and energy in to do well. I have a few questions regarding it in terms of population and such that hopefully someone is willing to answer.

What faction has the strongest NA population? I doubt there are exact numbers, something broad is fine.

Are there any good NA guilds that are progressing at a good pace?

What are the best tank classes to level? I only tanked in retail, all tank classes, and that is the same thing I am looking to do here.

How is the community here? Toxic, helpful, etc.

How is the scripting? Dungeons, classes, class balance, etc.

Anything else that someone coming from retail would find useful?

Thanks for your time and I look forward to reading people's responses!

Heya Cold! Nice forum name. Anyways, to answer a few of your questions. I've been around for a couple years now and I love the community we have here. People come and go but for the most part the community vibe stays the same. As for best tank class to level, I would suggest a paladin (personal bias here). Also, if you want a good idea of NA population, take a look at the guild recruitment section in each realm to see what NA guilds are around. Welcome to Warmane. Hope you enjoy your stay :)

Alright I check out the recruitment section, thanks!
