Empire is still able to at least compete with the top notch armies they gave empire quite some candy (war altar, prayers on bound level 4, hatred for the priest, core flagellants, rocket launcher, steam tank, outriders) while on the other hand they took away some stuff (no cavalry hammer, i really liked those ones, no two inner circle as core, no more fussilade, griffon banner technically gone, greatswords no more warbanner)
overall I think empire is doing okish but has lots of space to improve in the next army book.
