This is a bit late but I have been using WTFast for around half a year now I'm from Europe Finland specific and I can't login to the game without it any more it really does make a difference all my skills are executed a lot faster there isn't that weird latency lag when using skills in fast succession the program shows that I would normally have around 160 ping but with the program ( I use the premium one) it drops to around 125 ping it might not seem much but I can definitely feel it I will be using this program until they bring the official European datacenter at the end of this year
