I live in Australia and play on both NA and JP servers, and I have to say that the distance to the server makes dodging Titan's plumes like night and day. ON the JP server I can chill and just move out of the way when they pop under me, on the NA server I have to be in full flight predodge mode to avoid them. Plumes don't test your reaction time or ability, they test your distance to the server, and that's a little messed up if you ask me lol.
