In my opinion, there seems to be a general consensus that the cleric class is overamped, a problem that has only been exacerbated by the glut of spells and divine feats from follow-on sourcebooks.
My modest proposal to curb one element of the CODzilla syndrome: revisit the Spheres mechanic of 2E. Under this proposal, each domain would be associated with a group of spells. Those spells would be added to the cleric's spell list.
The Spheres mechanic also had the concept of Major and minor access. This could be simulated in PFRPG by having each domain grant one group of spells for minor access, and another, potential more powerful or useful set for major access.
Major/minor access was determined by the deities relationship to the Sphere in 2E, and that could be extended to PFRPG, or, a cleric could be required to take a domain twice to gain major access to its spell set.
Like the 2E Spheres mechanic, there should probably be a "universal" sphere of fundamental spells that all clerics should be able to learn such as consecrate, hallow, etc.
Finally, clerics would be allowed to learn new domains either through feats or through additional class abilities (or both).
The domain powers of PFRPG would remain.
