I thinkthat there are 5 things that they should really enhance
- the envoirment (looks awful, woods, plains, deserts etc etc)
- sieges (improved siege warefare, rams, catapults etc etc)
- better formations (for example the new DLC battle formations)
- naval warfare (I don't know how they did'nt implement it in warband when there were lots of mods that did it)
- more realistic animations (including death, cheer, impale, run, walk and combat animations)
most of these things have already been done by modders

but I for one think that it is really frustrating that the devs have left such important aspects out of the original game
