I'm very curious; people claim that the new book has less effective builds, but exactly how many effective builds did the old book have? Every single list I saw do well had Waltar, Stank, 2 Mortars, 2 Cannons, Engineer, Level 4 Life/Shadow, BSB, add Flagellants/Halberdiers/Greatswords to flavour. So I count 1. I count 1 now as well. I'm seeing no difference here.
As a note, saying you won a tournament with 2 war machines no tank and a General of the Empire isn't a valid argument; there are always exceptions to everything and especially when said exceptions are out of context and missing most of the important details.
