I really, REALLY hope the current spell hotbar just is unfinished and will undergo some major changes as the game comes closer to its release.
Same here.
The hotbar as it is simply will not be able to stand any spell caster class reaching level 5.
I am really hoping that this hotbar was just put together quickly as a dump-it-all area so that the developers could on and test other things. Meaning that not too much thinking and development time has gone into the UI of how to take basic actions, cast spells, use class abilities, consume potions and other items ... And thus, that proper design of the UI will happen in the future.
