I've recently started playing patch 10 and was amazed how much it had improved since patch ~7, its actually hard on legendary now, feels like shogun 2 legendary. And now patch 11 just dropped and fixed most the few remaining issues I had.
The game is SOOO much better now. I can say 100% that this is the best total war now, its not perfect of course. Don't need any mods to enjoy it now, only mods I use atm are 4 turns and trait mod.
If it had released in this state, and they made DLC that wasn't really bland and overpriced, it might have been my favourite game. Given me a real hard on for the iron age.
