As for the MP, plenty of people played it. I've played it extensively for months, but when GW2 came out I finally stopped. I tried going back a few weeks after and gave up after 10 minutes of trying to get a match going.
On the weekends during the events sure but I had a lot of problems finding games during the week. The MP ended up boring me to tears due its very limited scope and lack of variety so I didn't really care though. Their implementation of buyable DLC was borderline scummy shit too but that's a different rant entirely.
