I'm in Belgium too, and I was faced with the same problems : LS events happen start around 4 AM for us 90% of the time. We can do things earlier with a pick-up party, but even then, it's not uncommon for me to finish a BCNM run at 4 to 6 AM.
No matter how great the people in the LS are, it doesn't change the fact that NA players log in when we're about to log out.
That's why I've been thinking about creating an EU LS (also for those in NA that play early), but if some already exist ...
I was in Censor's previous LS (/wave Censor), before it fell apart (reasons still partly elude me), but most of it was from Québec, which didn't solve the problem of the schedules at all.
It is my opinion that we'd need a big strong EU LS with most EU players of the server. That or we'll have to choose between the game or sleep. Playing during the afternoon is just frustrating, and you end up blisting every "JP only" you see, as whatever the reasons for those comments are, it annihilates completely our chances to accomplish anything before late evening/night.
