I just got the book, and wow I am excited.
The main reason I love the corsair list is because if I wrote the eldar Dex, that is what the vehicle and infantry options would look like. I love that all the vehicles are BS4! As far as I'm concerned there is no reason that craftworlder gunners, who it can be presumed have been at their craft for decades shouldn't be BS4. I love the troops options. Bikers with scout and BS4. Wow. And war Walkers as troops. BS4 war walkers as well!
And the Hornet! It can outflank! And can take two pulse lasers! And holofields! And the corsairs can get relentless and 2 missile launchers. Wow I love this list. there is so much versatility and flying awesomeness.
"Oh, Sliscus, those gloves are amazing, where did you get them!?"
