Mortar: it deserved a price increase and a switch to the Black Powder misfire chart, it's strength should've have been touched at all (S3(6) MW D3 with large template, vs S3(9) MW D6 with a small template)
State Troops: The price increase comes from nothing, detachments got worse (counter charge and stand and shot, although they do count towards the parent unit's section of points, but they didn't improve in any way
Handgunners/Crossbows: 9pts for BS3? High Elf Archers are 11 pts with better BS, LD and ASF. Does not compute.
Cannon: I don't think the rumored 20% price hike was worth it, I could see 10% but 20 is a bit much.
I know people will argue that because of the improvements to captains and generals, the addition of wizard mobiles, improved prayers and whatnot, that the point increase to just about every infantry type is justified, that's like punishing Peter, because Paul came up and hit him.
