I'm planning to make a new too on this server and feel like blocking and dodging attacks with a shield is the style of play I want to go with.
Here are some questions I have regarding the current server meta and the community.
Disclaimer: I know that most of the questions are abstract and you never know the future, but I want to hear your opinions nevertheless since rolling a tank on a vanilla server is quite a commitment, you know

1. I'm active in late US PST time. I created a new toon and /who shows around 600-800 players for me. Are there any server activity like dungeons and raids happening this time? Is it possible to find a group for a dungeon / raid after 19:00 sever time?
2. Is there any demand on tanks here? Considering it will take maybe 3-4 months to level a toon, do you see tanks still will be in demand? Or are all guilds already have filled with tanks? Tons of tanks already leveling and fill the gaps?
3. As a plan B, in case I wouldn't be able to find spot in a guild, I'm considering organizing the PUGs by myself as an MT. How bad this idea is? Is it viable and how are people currently do PUGs around? In a 3-4 months?
Thanks in advance for the answers and cya in game.
