This may be an unpopular opinion, but I LOVE permadeath, and I think people who play casual mode are really missing out. The way that permadeath affects how the player defines "winning" and "losing," and the difficulty and tension it adds to the game, cannot be understated. I get how a lot of people get frustrated with having to restart a mission, 5, 10, or even 20 times. According to the game, I've played the game for 5 hours. According to my 3DS Activity Log, I've played for 19 hours. So I get the frustration. But I'm fine with restarting a game 20 times (which I just did with Chapter 6, the assassination attempt on Emmeryn), because I know that I will beat that mission eventually, which I just did with Chapter 6. And I've got to tell you, I had this big grin on my face for hours afterwards because I finally beat it. Making victory (or at least, my "leave no man behind" definition of victory) so hard-won makes that eventual success so sweet. If I had beaten that same mission in just 1 or 2 tries, it would have made it far less meaningful.
