Odin made our server melt yesterday. It's funny to see how Ragnarok went from under to somewhat over-populated.
As for the latency/lag issue, it's weird. I've had huge (I'm talking about 5-8s) lag spikes on Titan, I've also had really smooth experiences, and so did my LS mates who live in various EU countries. I have to play with a VPN on or I have crazy lag all the time, though.
It really depends on many factors such as ISPs and can't really be fixed on a case-by-case basis unless SE adds a EU data center, which they should consider to make it smoother for everyone here. As it stands, you have to roll a dice and hope you'll have a lag-free experience, which is unacceptable.
