Don't listen to this banned dude, hes on a mission or something to get people off this game.
On topic, you will find plenty of stuff going on for t2-t3 players depending on the time of day. Not sure where you are based, but during either NA prime-time or EU prime-time theres no way you wont find something happening. In fact theres usually so many people on both sides it turns into a multi-zone back and forth war for a while which I find really fun.
Past that, the off-times can occasionally be very dead, like ill log on at 10 PM PST sometimes and theres no more than 50 ppl on my realm total and no open WBs. Doesnt mean you cant get something started, but if you are more of a follower than a leader than yea you will find it dead sometimes. Only thing you can really do is get a group rolling yourself or do some PvE.
But honestly I enjoy it as something to log onto for a few hours everyday close to the popular times, and even during the off-times theres a good chance you will get SC queues especially playing as a tank or healer.
