The only thing I dislike about clerics is that they need wisdom AND charisma, where as most other caster classes are about one stat.
Sorc and Oracle: Cha
Wizard and witch: Int
Druid, if you want to be a pure caster: Wis
Also, the charisma thing makes dwarves not optimized for it, so it makes me sad, because dwarves are my favorite race.
That being said, I have two clerics, a retired cleric of Irori who was pure caster--all buffs and healing, with all the "remove" spells, too; and a new level 2 of Caiden Calien, who is a dwarf with an 8 or 6 charisma (just woke up and can't be bothered to look it up) and can never channel energy, much to the hate of my peers. She's a "battle cleric" who tends to be a second liner melee character or tank who wades through enemies to heal people only in emergencies.
Honestly, if the charisma requirement was nulled, I'd never play anything else. So instead, I play chirugeon alchemists and witches most. I'm not a fan of oracles. I want domains, not curses!
