It's not WSE2 fault, it's probably some international network traffic problem.
I always had 36-39 ms ping to crpg, now this ping increased to 54-57.
It's no matter if I use WSE or WSE2, it's no matter if I check ping in game or in console.
Right now trace route to crpg server looks like this:
  1    <1 ms    <1 ms    <1 ms  READYSHARE [192.168.1.1]
  2     2 ms     2 ms     2 ms  10.50.174.1

Few weeks ago all was fine, ping was 36-39 ms, now it's terrible, and my connection is same.
I still have good, below 40, ping to Warband native IG_Battlegrounds server:
  1    <1 ms     1 ms     1 ms  READYSHARE [192.168.1.1]
  2     1 ms     2 ms     2 ms  10.50.174.1

  4     8 ms     8 ms     8 ms  80.240.164.185
  5     *        9 ms     *     ovh.plix.pl [195.182.218.147]
  6    31 ms     *       31 ms  fra-1-6k.de.eu [178.33.100.161]
  7    40 ms    39 ms    40 ms  rbx-g1-a9.fr.eu [94.23.122.210]
  8    39 ms     *       39 ms  vss-5a-6k.fr.eu [178.33.100.26]
  9    39 ms    39 ms    39 ms  ns222848.ovh.net [46.105.111.21]
But my ping to Nditions duel server increased as well:
  1    <1 ms    <1 ms    <1 ms  READYSHARE [192.168.1.1]
  2     2 ms     2 ms     1 ms  10.50.174.1
  3     2 ms     1 ms     2 ms  unregister57192223077.c192.msk.pl [77.223.192.57]
  4     8 ms     8 ms     8 ms  80.240.164.185
  5    50 ms    51 ms    50 ms  interactive3d.plix.pl [195.182.218.80]
  6    56 ms    51 ms    51 ms  fr0-cr0.smartdc.i3d.net [109.200.218.77]
  7    53 ms    60 ms    52 ms  30ge-1-1.br2.smartdc.i3d.net [188.122.95.92]
  8    52 ms    52 ms    51 ms  213.163.83.191
So it looks like some deeper problem than new WSE version.
Something changed, but I don't think we can do anything about that. Maybe it will be fixed soon or maybe not.
I never had such high pings to European based servers. Hopefully pings will decrease again sooner or later.
