Make religious lore more relevant by having more feats enhancements and spellcasting use it as a calculation input.
Allow divine classes to choose their patron deity regardless of race. The portal between faerun and Ebberon has been open for a long time and it doesn't make any sense anymore why deities are race specific. For instance humans are from both worlds therefore they should be allowed to pick a patron deity from either world.
Allow aasimar healing hands ability to key off of the higher of wisdom or the attribute associated with their form feat.
Give paladins more class specific spells or ability to make up for the power gap between paladins vs the additions given to clerics and favored souls in patch 36. Paladins received nerfs while these classes were buffed.
Add an enhancement to sacred defender that allows a paladin to expend a turn attempt to add charisma bonus to a.c. while using a shield.
Have religious lore add its value as a bonus to healing amplification for paladins.
Have religious lore add a bonus to melee power for paladins.
