Guys, let's be real here. Those of us on the East Coast were spoiled. It's going to take time for us to adjust to having a higher latency... but unless you now have over a 150-ish ms ping, you really shouldn't have any issues. (Some people were actively raiding with higher than that and they were fine, but reaction times will vary.) We just need to be less greedy with our timing. Every AoE is avoidable, but we just have less leeway -- less time to be a little extra greedy. We just need some time to adjust.
I *do* feel bad for the EU players who are now experiencing unplayable ping, though. I'm in the camp that thinks they should be offered a free transfer. Still, I can understand and appreciate the frustration of having to choose between leaving their friends behind and playing with an acceptable ping. Back in 1.x days, I played on a server that was eventually designated as a JP server (Aegis). Seeing as most of the people in my LS were ex-FFXI players, we had known each other for years and were very close. Many of us were international players, so the decision was made to stay on the JP datacenter when ARR went live. I knew my latency issues... I knew how I struggled to beat Ifrit Ex simply because of lag... but I still wanted to play with them. So, I leveled two characters during the open beta -- one on the NA datacenter and one on the JP datacenter. It became readily apparent to me that playing on the JP datacenter would be a huge sacrifice for me... I wouldn't be able to reliably dodge. I made the hard decision to leave the server and to go to an NA datacenter. Many of my friends were upset with me, and the leadership of the previous LS even said to me... "Don't come crawling back when you can't get anything done." I left all of my friends behind, but I had no choice... If I didn't leave, FFXIV would become nothing more than a glorified chat program for me. So, the situation is difficult enough for EU players. Please don't make it harder on them by telling them they deserve this situation because they didn't move earlier or should just be 'okay' with how things have played out. There's always going to be people who are placed at a disadvantage when a huge datacenter relocation is made, but let's try to be a little more understanding of their situation?
