After playing Aztecs with Autocracy, I do agree with most that some of the tenets should be changed to make warfare a way to address some of the types of deficiencies that a militaristic state would probably have; those being a lack of culture/tourism & perhaps some buffs to the diplomatic aspect that is supposed to be a strength of the ideology (according to the devs).
I was thinking that some of those weak tenets that people are saying are not so good (like healthcare, fort borders, futurism, espionage) ought to be changed in such ways that make warfare help improve tourism and diplomacy. Perhaps an idea would be a tenet change that would give an additional WC vote for every capital that your civ has captured. Or perhaps give some bonus tourism for each military unit you kill (I'm sure Joseph Goebbels would have a movie or two to make about your victorious battle

). United Front should maybe make all city state allies grant you units instead of just militaristic ones (because as an autocracy, I tend to have few CS allies because I tend to conquer them instead), although perhaps the military ones could do so more often. And I think the universal healthcare tenet would probably work better if it helped you heal your units faster instead of more happiness.
Maybe these aren't ideas for level 1 tenets, so perhaps there would need to be some rearrangement, but Autocracy does seem lacking a bit in helping a military style victory, which is what it professes to do.
