Are there enough people on blue? Just curious

"too low" depends on what you want to do. I've been able to find consistent groups in Unrest, HHK goblins, City of Mist, and Karnor Castle. That being said, they might not be ideal sizes or compositions. You will likely need to solo some of the time. Going to EC during peak hours or weekends will likely allow you to get cheap mid range gear and buffs from the remaining players there.

That being said: If you want a 6 man group every night in any zone you want it ain't happening on blue.
