My only issue with the game (aside from the 100GB download on my 256GB SSD...) is WB's EULA. I declined it so I'm playing in offline mode, but I it rubs me the wrong way how WB doesn't care one bit about the player or their experience, they just see this as a pure marketing source. Now that the market is leaving, I'm sure they are going to be selling everyone's data ASAP to get the most out of their marketing scheme.
Then again, this isn't the first game or company to monitor what we do and sell our information to third parties for marketing purposes. This is a practice that's been happening since before the Internet, but it's still irritating that if you want to play any of the online features, you have to agree to let WB monitor your PC, transfer your profiles around and their discretion, and even install programs on your PC without your immediate consent. I wish there was a way around this, but so far I can't find a way.
Also, the captain speeches are about three times as long as they were in Shadow of Mordor. At one point I thought SoM's speeches were long-winded but holy hell they go on forever in this game. Especially if they kill you. I had one captain gloat for almost 20 seconds straight and I couldn't skip it, then I had to watch everyone scuttle around in the army and then watch Talion slowly stroll up to the castle again. It severely breaks the flow of the game.
