Let me add a thing to the list. The entire game sucks. It is absolutely fucking terrible, the AI both on map and battle is horrible.
I sometimes wonder whether people have either put RTW on a pedestal or played to many mods to remember what the original game was like. In it's state now it's still buggy as hell with the BAI and CAI being pretty bad most of the time and making some odd decisions or no decisions at all.
Rome 2 is pretty similar to Rome 1 in terms of CAI + BAI in my opinion. My only qualm is slinger spam armies but that seemed a lot more common earlier in my campaign and seems to have petered out now.
Edit:
Watching the angry joe review I honestly can say I haven't experienced a bunch of his issues. Like the complaint about never been declared war on or never facing big army stacks. My Egypt campaign has been the complete opposite of that. I've been declared war on tons of times and have to keep 3 full stacks across the rear of my territory because I've been invaded more than once by full stack armies.
Most of the bugs I've not experienced. But then that's more due to fortune I suppose. As for saying its worse than Empire for BAI + CAI. That's just stupidity. BAI in Empire is the worst I've ever seen it with enemy armies bugging out on the edges of maps. It was impossible to be invaded by sea and the economy was so borked you could earn millions even when completing mismanaging it.
Siege AI in Rome 2 is bad. But then it always has been and it was only improved in Shogun because they simplified it to climbing over walls with hooks (and even that took them all of Empire and Napoleon to get right).
The flag capture points are definitely bull shit. I think those should have been done away with after Shogun. They never really worked even then.
I suppose all I'm saying is that, yes there are bugs, but most of them are issues that have always been there and I think people were a little naive in thinking CA would have magically changed and would release a game that didn't need 6 months + of patches to get right. They haven't done that since Medieval 1.
