I really like the look of these - although I admit that I find the background makes them hard to see clearly for me (I thought the Muyib with the panzerfaust at the back was a Ragik!).
Actually using the rules for the sub factions such as fireteams might help. It helped when I played those djanbazans so hopefully my muyibs will be better next time I play them.
Link teams are pretty "OMFGWTF" good. Haqq is good at mobility and has very high WIP anyway, and being in a fireteam really enhances this enormously (I mean, it's good for any group of models, but some definitely benefit more than others).
Don't forget that Qapu Khalki can have a second mini fireteam as well, thanks to the Odalisques and Sekban having the "Haris L1" skill.
Also, remember that Hafza can make up the numbers in any link team!

Oh and focusing on the game or objectives and stopping making jokes 90% of the time might prove a bit useful from time to time. 
As a Nomad, I am 100% for making jokes for at least 90% of the game!
