Just one or two weeks ago I was in 30ish lvl area and it was nearly empty. I felt like playing single player game, couldn't find party for bams there. But now, its full of ppl! I even had to wait 10 min before I could enter the server. Its very nice feeling to see ppl running around again, etc. Though server lag is apparent. So i think it was very good move for tera to go f2p. Hope that ppl that come/return to tera because its f2p now will stick around for longer.
