I believe there are community forums where you can ask such questions on the site. Since using it I notice a difference even when leveling gathering. It just makes the clicking on the veins/nodes/trees etc so much more responsive. Some might say if I am in the UK why not just play on a NA/EU server, but I am on Masamune because of my wonderful free company who I discovered prior to ARR's launch and are now my best friends in game so I have little choice in the matter. The game is about who you play with rather than what you're actually doing for me, so I have to make do. WTFast and also the network card reconfigure definitely helped a lot. After I first used it I tried Hard Mode Titan with a free company friend and we pretty much 1 shot it with a JP duty finder group as we were easily able to dodge all damage as if we were playing a single player game and it felt wonderful.
