Depends on where in the EU. A fair number of Western European players (think, UK, France, Germany, etc) play on NA servers, although crossing the Atlantic and then all of continental USA does take its toll on latency. It's playable, but not great. RP shouldn't be affected, however, if you're interested in trying different servers out.
FFXIV's supposed to be playable content-wise until you have a ping over 200ms, after which dodging mechanics is more an art form than a reaction. Most people aim for at least < 150ms and < 100ms is gonna be better. Gaming VPN services like WTFast, PingZapper, Mudfish, etc can usually improve this, but physical distance does still factor in.
You can get a basic idea of what your connection will look like by pinging the lobby server for each datacenter. (Any basic command line will do, like cmd.exe on every Windows PC!) You can also run a traceroute using tracert in the command line (windows) for more details on what the connection looks like each step of the way.
