I'm not trying to be a troll, here but from what I've read and seen from my self, it seems like the pop is falling back down.
It seems like the city is popular, but the leveling zones seem to be empty again. I know it's probably top heavy, but a well populated MMO always has a decent amount of people in the lower levels. Another thing I queued up for PvP on my mid level toon and I cound't find any matches, waited like 15min and said f it.
It's a shame if this F2P conversion doesn't work out, it's a great MMO, but I honestly don't know what the future holds for WS. I'm hoping putting the game on steam will increase the pop like it did for Tera.
