There are lowbies, you just have to search for 'em. You can narrow down the search, but gotta remember there's not a whole lot of people playing from 3-12AM.
Also, there's the fact that less people play on the EU servers. Try asking people in your lvl range for an invite, or start your own team 
I find there are plenty of teams going on my lowbies :3
Just have to ask now and then ^^; ]
Good luck, and if you see me online on either character below, just ask 
<3
Also, remember what the current situation is. Ahead of i11 a lot of people are waiting on the new sets before rolling another lowbie alt. I know a lot of people who are currently actually working on finishing high level toons ahead of the new issue and making a new character, so I guess there could be a lull in lowbie action.
Around various SG sites and forums there's a lot of chat about what characters people are going to be making in the new issue, so I think there will be quite a fw new toons running around come launch time .
Pre-issue periods are always a transient stage for people.
Also if you see high lvl toons on atlas standin and doing about nothing it doesn't hurt to ask em if they might have a low lvl toon or something...
What ever...
Just get it...
Over with all ready...
Try sending me a tell (@mereman). I have a few low lvls. Mainly Defenders. I'm on most weekends. But if my SG calls I may have to leave.
Happy to be on Defiant.

Just a quick question here folks, are there any people who play low level characters at the weekends? My play time is very restricted so I don't get on much appart from the odd evening during the week and most weekends, the problem I've got is that I'm finding it extremely difficult to get a team together as no one is playing in my level range.
My current mainly played characters are Chill Time a level 8 Ice/Ice tank and Kung Fu Mike a level 7 Martial Arts/Invulnerability Scrapper. When I have a look at the lfg tool I don't see anyone in my level range and when I flag myself as lfg I don't get any invites, when I used to play on the US servers I couldn't go 5 minutes as my tank without getting a team invite. Has the population of the game dropped off to such a level that there are just no lowbies around anymore?
