The new assault rules are ok. They've wiped meltaguns practically from the face of the earth, but they're decent.
The new vehicle rules are crap. Ordnance becomes even more of a gamble, even if you can move and shoot it [which is crap, I like the image of a tank crew boltering down and firing an enormous gun], dreadnoughts become unstoppable against almost anything [although granted with the new assault rules a power fist weilding character or witchblade warlock stands a good chance of beating it since they can't be singled out. Power fists will be all over the place like greatweapons in fantasy], and CLOSED TOPPED TRANSPORTS ARE DESTROYED.
A marine assault army can use bikes and assault squads.
A chaos army that's anything other than undivided? Ummmmmm....we could have....42 point flying aspiring champion chosen? 42 point flying possessed? 40 point bikes that can't take advantage of cover and die just as easily as a grot to heavy weapons? No wait, the grot can take cover, nevermind.
I've heard a rumor that vehicles may still be able to move 6", unload and the unit inside can assault. This will tone things down a little and make the new rules not as bad. A unit has to be able to unload and assault. They really need to be able to move, unload, and assault, but if I have to take stationary or not at all, I'll choose stationary.
TAR: A-ok.
TVR: utter crap. The only thing I like is move and fire S5 or less. Tanks can now become mobile weapons platforms, as they're designed to be.
