Here are my disappointments
1. Mortars; just why would you do that
2. Handgunners, why would you make an already sub-par unit more expensive?
3. Swordsmen point increase, ok the initiative stabiliser was long overdue, but putting them up?
4. Magic altars are for celestial/light colleges, and I know I can bring them as a rare and have my wizard lord from a different college, but dammit I like my army to be themed!
5. Greatsword standard bearer can't take the griffon banner
6. No fix for pistoliers
Here are the things I like about the new book
1. Cannons are finally costed appropriately
2. Spearmen now look pretty attractive as a parent unit choice
3. The hurricanum is awesome from every standpoint
4. Detachment rules look better, and they can count towards core requirement
5. Steam tank more reliable
6. I finally have a reason to take a General over an AL other than "I hate religious nut-jobs"
So I guess you could say my reaction to the new book is about 50:50, I'm gutted that so much of the list has been... gutted, and I'm really sorry for the guys who built their lists on flaggellants and war altar only to find your flags are now crapola. New books where big chunks of the list become non-choices is never a good thing, maybe we will see the return of flaggellants, handgunners, swordsmen and mortars with the 9th ed core rule book, or maybe we'll have to wait for our 9th ed army book and hope they give the project to someone with actual ability.
