I played against a friend yesterday and between the two of us we took all of the new units. I was most impressed with the Wyvern's they truly are nasty. There first volley they killed 24 out of 30 of a blob behind an Aegis. The other highlights were the Primaris Psyker's twin linking units was nice.
My opponent brought 8 bull ogyrun's. They did better than expected, he used them as a shield for his command squad with camo cloaks behind an aegis granting them a 2+ cover save. They also put a hurt on my 50 man conscript squad with attached shenanigans. Pricey for what they did but it was effective, we came to the conclusion that you could probably get the same effect with 6 and attaching a priest.
The new orders are great, especially the shoot and run, and bring it down's changes especially when the unit has prescience cast on it.
