Hellicary raid maker is not working?

I try to join raid and always some people have left town or dc so the raid never get off the ground, and the raid keep finding new players even tho it cant get going, when people notice it they leave and new people get tricket into joining

In order to complete any task, such as kill Lassal level 1, I need to go in an 8-person raid consisting only of a squad.
The game does not give any hints on how to complete the task.
Blizzard - Change it, so I can do this quest without a squad.
