to be honest, adding quests and rpg elements are good designs. instead of only items like in warhammer, the quest rewards can easily be factionwide bonuses, unlocking special units, hell, even an unique building chain. that also makes the players feel more involved in the game. special abilities on generals are fine. even in warhammer it was mostly morale or speed enhancers. if we take out warhammer magic.
judging from warhammer sales numbers, you don't matter :))) just kidding. 100% historically accurate = you are dreaming though. that is no longer a game. problem with rome II/attila was because a designer at CA decided the defend button needed to go to create chaos so players would have more micromanagement in battles. this choice caused alot of problems, one of which was the blobby mess you saw. it was why formed attack was patched in. if you have played warhammer I and II you would know this problem has been solve.
warhammer series had a huge engine update. ca might have upgraded the engine even more for the new game.
@thread ca just released a single cgi trailer, and negativity is up the wazoo :))) china will always be a hard sell. too many haters :) good luck to CA.
ps: I have always hated the first gunpower total war game because it introduced the hated, loathed firing cones for range units. it made sense for primitive gunpowder units, but 100% retarded for archers and horse archers.
