Hardcore Raider, Just joined!

Hello!
I just heard about this server from a friend.
Raiding Hardcore currently in Live, And i always liked Wotlk alot more than any other expansion.

So here iam.

What can i expect from this server?
Is there decent guilds?

Raiding?
Alliance/Horde?

Also, i currently main Hunter on Live, But i have some sweet memories of Rogue/Mage from Wotlk, So, How are these classes in the current state of the game?

Its all good whatever you pick, you can join

Expect it to be harder than retail
