There are a lot of new rules that are confusing people (Shunt move in the scouting phase, Dreadknights in a Storm Raven, etc.).
But what is surprising is that there are a lot of people who think that there are errors in the new rules that the Demonhunters had all along.
To give you a couple of examples:
#1. Everyone is surprised that you can fit Terminators in Chimeras. Well, that has always been the case, and it is nothing new to Demonhunters players.
#2 . Strike Squads Deep Striking. Here is a news flash: Grey Knights in power armor could deep strike in the old codex. So everyone freaking out about it being a misprint are wrong.
There are other rules that I have read and heard, but that is enough to show my point.
