There's some great posts and discussion about the new system over at both Werit and Wizards and Wenches, if you want the lowdown on the new system I highly recommend you check out both sites.
I'd also like to give a shout out to:
Breakfast at War - These folks just got to 100 posts and over 10k hits. Go have a read and you'll find out why :)
Way of the Chosen - Rivs has put up an interesting post about why he could never be a carebear.
Tank Wall - I only recently discovered this blog. Great name for a blog and he's playing a Chosen. Sensible chap clearly. Well worth a look.
Biobreak - If you didn't catch the news last week, Syp has moved on to a more general blog. It's looking good, but then that was a given.
The Greenskin - Delves into WAR's crafting. If you've not paid much attention to crafting before, this gives you a good summary of the different types available.
