Yup, i think you'll be surprised of the lvl of high end guilds on the eurosever. The guilds are more concentrated where on the US servers the hc guilds are more spread out to avoid competition from eachother.
Just to give you an example there are 3 guilds that cleared VP already for quite a while.
What you have on splitpaw is:
1) Fable: only true hc guild, expect high playingtimes and well eq2 comes before everything else here
2) Validus: semi-hc with 75% attendancerequirement and 5 to 7 raidingdays a week. In general they stick to normal playinghoures but on an exception they will try to go for an avatar
3) Unity: semi-hc like validus but with a bit lower attendancerequirement (60%) and 5 raids a week.
These three guilds have been the top3 guilds for a very long time now and they are the three guilds that already cleared VP.
4) Nastrand: guild of former hc raiders that didn't want the high playingtimes anymore but they still can be seen as semi-hc. They finished VP as good as.
5) The vision: new semi-hc building up a force from 0. Think they are still in T1 or T2 but i expect them to grow.
You have a lot of decent family raiding guilds too like Holy Grail, Amenta, Dark Haven, United Kingdoms and many more. I think for the moment only Holy Grail is in T3. And the rest is in T1 or T2
