I was thinking that maybe spells should be changed so that spellcasting classes do not get bonus spells from their respective mental stats. This will help balance spellcasters at higher levels when their primary stats reach gigantic numbers and it could hep reduce book keeping at later levels. Also, it has less of a negative impact on the classes at low levels because their stats are lower. However, due to the relative weakness of casters at low level anyway, maybe they should add an extra spell per day/memorized for first and 2nd level spells.
This change can also help make other stats more important for spellcasters, thereby encouraging a more balanced stat decision for a player with a spellcaster.
What are everybody's thoughts on this idea?
