Maximum of 8 skills at a time

This game is going to have a minimal amount of hand-holding, so you really need to get used to that. It's systems will benefit those who take the time and effort to tweak their stats and skills to get the most out of the mechanics, and that includes swapping skills in and out.

I wouldn't expect any changes to this, as the game clearly demonstrates this design mentality. It is quite unforgiving, and rewards good play (if you don't die, you don't have to recast all your auras). While I don't disagree it would be nice at times, I prefer that they don't compromise their design philosophy and keep the game in its unforgiving form.

in my opinion, there should be 1 extra slot that's only useable if you have Move Only on any hotkey, because i don't think it should take up a spell keybind for an almost mandatory movement command

You are already limited by the number of sockets that you have. Why should there only be 8 skill hotkeys? There shouldn't be because it's a design throwback.
