Is it possible to change servers?
in order to change servers, you need to pay gems and it costs 1000 gems to get onto the most populated servers like desolation/ gunnars hold. Unfortunately guesting does not work with WvW and you just get defaulted to your standard server at that point.
The amount of players is also dependant on what time of day your on, I find the busiest times are around 7pm - 10pm, nothing like getting all pumped up for a WvWvW game and then seeing that theres a queue of 20 to get in
