The game is pretty much unplayable for me, but my friends don’t seem to have any issues, but our traceroute shows totally different routes to the server where we play (EU-Desolation).
Here’s my route that seems to be broken (500+ ms is pretty common):
5 14 ms 14 ms 13 ms tuk2-tr1.dnaip.fi [62.78.107.57]
6 14 ms 15 ms 13 ms ae5.stk30.ip4.tinet.net [77.67.67.197]
7 * 226 ms 222 ms ae5.fra61.ip4.tinet.net [141.136.107.218]
8 231 ms 238 ms 232 ms cdnetworks-gw.ip4.tinet.net [77.67.71.122]
9 216 ms * 225 ms 206-127-157-94.plaync.com [206.127.157.94]
10 230 ms 207 ms * 206-127-157-102.plaync.com [206.127.157.102]
Here’s a route that does not have that many issues (50 ms is playable):

If you create a VPN connection to some other network and play through the VPN tunnel, everything works fine if the VPN where you connected to does not then travel through the same tinet.net machines.
I think it’s more likely that some tinet.net servers (ae5.fra61.ip4.tinet.net? cdnetworks-gw.ip4.tinet.net?) are causing the whole issue, not PlayNC servers or different ISPs that we’re using. Of course, it would be nice if NCSoft could politely ask tinet.net to sort it all out, if it’s really them that’s causing the whole mess.
