Fateweaver can make a sweet wizard tower landing pad for his bros. Oh and he swoops. yippeee!!!
On a serious note, the fortifications seem ok, but theres no army that really needs them and theres none that if the points are there it isnt totally worth having. Flying MCs have the most potential out of anything (way, way over fliers). Vehicles are almost completely underwhelmed with the new rules. The power weapon thing sucks for those who just wanted to have something look cool, but it is nice to see the options. The allies matrix is really awesome for casual games where fluffy mixes make for a true army, but has huge potential to be broken, I doubt you will see many tournaments supporting it, however it has great potential to influence how doubles tourneys will work. The crb powers are not really OP or bad, so there is some options there, although I laughed the 6 (which in fantasy is the 'ultimate') for fire is just a meltagun. The 29784536 new special rules/keywords are a bit daunting but most are pretty much things that already exsisted but fell under misc. categories.
Overall, I like this edition a whole lot more. It will be really exciting to see how things unfold in the coming months.
