Hmm... Clerics. When I laid the foundation for my Chronicle, there were 3 core classes I was not happy with:>
Sorceror (removed it, transformed Psionics into 'Sorcery')
Fighter - entirely rewrote the class
Cleric - Initially, removed Heavy Armor, everything else was same
My Likes for the Cleric are:
Spontaneous casting - very good idea
Domain Spells and Domain Abilities
My Dislikes Are:
Heavy Armor Proficiency
Cleric Spell list is too broad
Cleric spellcasting has little to do with nature of deity - Goddess of healing can cast Flamestrike for isntance
Domain abilities, and Domain Spell lists are not even close to relatively balanced - there
are clearly overpowered domains, and clearly underpowered domains
While it did take a while, I eventually rewrote the Cleric - the core concept was to change
the Domains and their spell lists - each domain now has 3 spells of each level on it, and there is also a 'general' lists that all Clerics have access to
Now the spellcasting is very thematic to the deity in question.
I also changed spontaneous casting from healing/inflict to one domain list of your deity
I also added 1 or 2 aditional domain abilities to each domain to better 'balance them'
versus each other - each domain is now MUCH more useful
