While it makes clerics weaker in the overall game, I've always preferred clerics with access and limited access to various 'spheres of influence' based on the portfolios of the gods worshipped, like it had been in 2e and prior. The fact that Thor the god of lightening provides the exact same spell access as a priest of Anubis, just doesn't make sense, thematically speaking. I'd rather differentiate clerics by the influence of their deities, providing specialtists like wizards, instead of all clerics being 'generalists'. And perhaps having granted powers (Su) and (Sp) more closely hewn to their gods influences and specific goals, in place of some of the loss of spell access.
I understand that this was changed in 3x to make clerics more playable and inviting to an adventure group. I think this diminishes cleric in flavor, despite enhancing them in power.
I don't expect this to change in 5e, but thought it was worth mentioning.
