How alive is this game?

I've played RO2 back on the release for a couple of months and now I would like to get back into it. Is it worth it, is the community active, how many filled servers are there usually in the evenings? Should I be getting the Rising Storm add-on (or whatever it is) to find the most active scene?



Reason I'm asking this is because downloading the 20+ GBs of the game is a pretty big deal with my current connection and I dont want to find out that there's one server that has decent amount of people playing.
