The only controls I had a problem with was the lock-on, and even sorted that once I realised how to hard-lock. Three different lock-on types is stupid though, so hope that gets changed. My only other complaint regarding gameplay was how chaotic the battles became late on. The robotic army guys were a pain in the ass to fight since if you weren't getting shot from behind, you were getting charged and if you're not looking head on to the guy charging (and often there's multiple chargers) you can't parry, nor can you do anything once you've been grabbed.
Noctis' voice I thought was pretty okay. His dialogue was pretty decent, it was his battle grunts that pissed me off. For the longest time I thought it was Gladiolus grunting away. Prompto was fine, he just needs to speak less, he's always commenting on things or doing exaggerated "WHOA"s. Gladio was fine, and Ignis was okay, if a little pompous at times.
Not going to comment on Cidney other than the name (which should stay Cidney) since I found her quite inoffensive.
