I'm new(ish) to Titanfall -- questions aplenty! Amazing game? Yep. TL;DR is that I've NEVER enjoyed online shooters before, and Titanfall is my favorite FPS experience in years. 
1) I've only played Attrition and I don't use voice chat (making teamwork hard). What other modes are fun and have a steady base of users?
2) I started a couple of months ago, and haven't bought the expansions yet. I want the extra content, but are there enough players out there in those maps/modes to make it worth the purchase?
