Is it possible to play on the server with 10 friends

Hey there,

I know there are around 200-400 players on the server and I can imagine it is hard to form raids and rdf hc BUT my question is - can my group of 10 friends play this game normaly and enjoy it? Is it scripted well? How would you compare it, regarding scripting, with wotlk?
If we were doing raids together in our small circle of people, how many players we need to have minimum in raids to be able to do hard content raids and normal ones.
Any more information you can provide extra would mean a lot.
We dont have a problem with “dead server” but we want to be able to play it normaly and enjoy it

Thank you
