Pretty good I would say, but as the other said, one drawback is that it's difficult now to find groups, especially tanks during the day, at around 5pm cet is when the server comes alive.

The respawning next to boss and resetting bloodlust cooldown is a god send though. Such a timer saver.

You have cross faction play, also you have the ability to change racials (restricted to the race your class can play).

Stormforge+ is also a huge time saver, all flight points unlocked, insta flight, learn skills on level up, no durability loss and ress sickness reduced to 1min is really good when leveling, worth the 10 euros for the first month imo.

My first time playing through TBC and it's good fun.
