The main highlight of the game from the viewpoint of the new units was the Hell Talons, my opponent (Eldar) only had a vampire so there were no intercepts taking place, they did however cause a significant amount of damage to ground forces, being able to hurt tanks in a meaningful way with them under these circumstances was a refreshing change to the Hell Blades I've tended to use in the past (a four strong but broken post-engagement formation of falcons withered away under one ground attack, and a couple of wave serpents full of aspects under another).
Can't really comment on the up-gunned Ravager, as thanks to the Eldar's silly special rules (aka popping up skimmers) the only targets that he was able to open up on over the game were some Guardians where the titan killer change didn't make any difference and a Warlock titan, which owing to it's silly Holofield was able to shrug off all the shots

. With a little luck my next playtest game will be against an army featuring some better targets to see what it's capable of...
Generally I missed multiple forlorn hopes, but the ability to take several Raptor formations goes some way to making up for it, like the new Hell Talons and think that the Oblits are now more reasonable, although still a sore thorn in my opponent's side.
Very interested to see how Steve got on with the Decimtor and Feral horde...
