I'd like to see what you guys got on this list I run lately to quite some success.
It's not that I need help how to improve it, but rather what you think are it's weaknesses, it's strenghts and how you would react to it, if it was played against you.
So basically its:
Waaaghboss on bike, fully kitted,
PK, Cybork, Squig,
BP (because he's with the koptas)
BigMek with ShokAttakGun
3 x 7 lootas
3 x 20 Shoota boys with nob
PK,
BP
5 Koptas, Big Shootas to go with the Waaghboss.
1 Dakkajet + additional supashoota and fighta ace
Boomwaggon, Ram
6 flashgits with Doc and Baddrukk, (hes a mean baddie

), moar dakka, shootier
It's quite the shooty list, i think, and my enemys tend to have problems what to take out first, and every unit has the potential to put some hurt on them.
The flashgits mostly do not make their points killing-wise, but they do draw attention, which is fine by me.
