[AoS 2 - Hedonites of Slaanesh Discussion]

I don't know if this topic is already finished but I was wondering about building my slaanesh army. In the battletome is written that when you have chosen your host your army must contain a number of battalions. 

Like a Godseekers host must contain 0-2 epicurean revellers and 2-4 seeker cavalcades. Sounds lkke a must have without I'm not able to play this host. But I couldn't find any tournament list that contains this amount of battalions while they're a Godseekers host. 

Main question: is my english this bad or isn't it a must that I need to play a special host? 

Thanks for your help!
