After lots of success with a previous list I posted, I wanted to revamp it to make it even better (hopefully)
The chiefton has a stormbanner and no ward save... i know, i know.. but I put him in the bell unit that is 5 wide (stormvermin) and since i have a fangleader, musician, and banner... my chiefton sits in the 2nd row. I only activate this baby when i am facing a better gunline than me/i don't get first turn
I know i don't have clanrats... I don't care

. Slaves do pretty much everything clan rats do, i have a 18" leadership bubble, and engineers in every squad (until right before
CC.... then they shoot their shiny stuff and redirect). We don't play blood and glory.... in that case i would use a list of one unit of clan rats, one unit of stormvermin and three slaves.
I have a very expensive warlord.... yes he could be a target... but i have so many, my opponents tend to not care about him until they find out he has a Fellblade.... by then I should have my gutter runners/rat darts in position to save him from cannon fire.
