I understand the reason for class removal, but at the same time, yes I do miss picking a class.
This. Classes have always been a big part of RPing in TES. Your character is an agent. This automatically makes you ask questions: Who did you serve, where did you receive training, and how clean were your methods? If I want a more unique roleplay, I pick a custom class and choose skills according to that. I loved Daggerfall's system. I also miss attributes. What do health, magicka, and stamina say about my character? Nothing. Maybe I'm a warrior who has a blessing/curse; I'm incredibly strong, but very, very fragile. I also miss having a skill for everything, I don't know why, but I just had more fun that way. I hate the perk system, it kills all sense of progression.
I'm not going to say that the game is being "dumbed down", but its been streamlined no doubt.
I'm also very intimidated by the amount of freedom I have at the beginning of the game when there is no class system. I will level up five times and not spend a single perk because I end up changing my mind on my build.
