Bought the 4th Edition rule book a few weeks ago, read through the now two month old White Dwarf article (I've managed to get really behind with my mags!) and skimmed the book a bit and I was wondering whether people thought their armies were more or less powerful.
The new rules seem like good changes in most places - either sensible clarifications or alterations that make it more like a swirling fight (more close fire fights with better rapid fire and more destructive combat with everyone within 2" getting all attacks!).
I think the Orks will benefit a lot with my style of play - better rapid fire and everyone within 2" having full attacks means a full mob of slugga boys will be hellish destructive *drools at the amount of dive he could roll!* Although there is the downside that Grots no longer act as a perfect shield (on leadership test and the enemy can choose to target my Orks) I think the general destructiveness of combat should make up for it for me
If you want to see the changes from 3rd Ed, go to the 40K section of the GW site and click the "
Warhammer 40,000 Downloadable Rules" link.
