The thing with spells is that there arent that many of them altogether. And out of those only some are really useful.
So... being limited to 3 or 5 spells isnt that of a problem, really.
All the info one needs to see which spell is what and how useful it might be is contained in the spells in-game descriptions.
It isnt the best possible thing to have, true, but it is the consequence of adjusting gameplay to support focus builds versus hybrid builds and vice-versa that was going on back and forth during the last stages of the beta.
I mentioned that in replies to your previous threads, geezer.
Larian tried to find a balance between the two but i feel they ended up with a system that is still slightly leaning towards focus single class builds rather then classless builds or hybrids. This includes the character creation presentation, companions, addition of henchmen and other more mechanically related things.
Another thing, im not sure if this was changed in the latest patches but previously... you could not use a spell that is restricted to a level higher then you are.
So, while you are level 5, you could not learn or use spells that were locked to level 7, or 10. Regardless of how many skill points you invested in that specific magic.
Unlike weapons, which you could use - with a penalty.
