People pay a lot of money for these books. They actually even HAVE to if they want to continue playing with their armies. And what do they get in exchange?
- Typos you notice on the first read.
- Artwork that becomes worse and worse,or is even missing from the book ("New Art" watermark)
- Badly written rules (poorly worded or unclear)

So what Games Workshop should do this time:
- Actually proofread the book. Players notice typos on their first read, it's very offputting.
- Properly playtest the rules: players quickly come up with several questions as to how some rules actually work.
- Change some of the rules and names that go against reason, lore and proper taste (Ripperdactyls?)
- Employ the talented artists of old again, those who had a passion for the lore.
- Read the forums for additional feedback. We wanted Monstrous Cavalry, spawnings, a new really big dinosaur, Carnosaurs that live past turn two,... Not a Troglodon.

And most of all: take your time! Don't rush things like you did now just because your precious Space Marines were up for yet another redo. It's obvious this book was quickly finished to get things out of the way, which is insulting to players. It is hard to imagine the rule and fluff writers took their time and consulted dozens of people with so many errors still present. Where's your passion GW? You couldn't even be bothered with some nice scenery for the gallery..
