Can't believe people in here actually don't want EU datacentres, this community is so full of shit at times, this game is never going to move forward as long as there are so many apologists around to defend SE.

For people saying Learn to dodge I have completed Titan ex and have very few issues myself with latency but thats only since I have been using a VPN and I don't think its acceptable to pay extra because SE decided to have its servers half way across the world. (lets not forget that not everyone uses a VPN and it only takes 1 tank/healer to get knocked off the edge and you may as well wipe)

I don't have to do this with any other MMO, hell Rift a fee to play MMO has EU servers, so don't give me that bullshit that it "costs a lot of money". If Trion can do it SE sure as hell can ... they are just too tight and lazy to bother.
Your situation actually sounds just like mine.

I'm not sure if the issue with aoe-lag is because of the location of the data-center or what, but it is quite inexcusable.
I personally have to use vpn to be able to do any of the higher level content. Titan HM without vpn? - Can't dodge anything = wipe, Garuda Ex. without vpn? - Run to the bubble but never get the buff = wipe, not to mention stuff like esuna can be cast while running.. With vpn no problem though, cleared all ex. primals other than moggle mog (which I haven't tried yet) too, for those about to say I just suck and need to learn to dodge.
And to those who think it's unreasonable to point finger on SE for these issues, I think it's even more unreasonable to point the finger at the gamers and their connections. Personally I have a 100mbps connection, and no problems with other games whatsoever. Make what you want of it, but i think it should be good enough.
