No spheres for me. I like an element of predictability.
At the very least, all PC clerics would gain access to certain spheres, including healing. So I guess that's pretty close to what Yora is saying.
If you're playing a death priest who logically shouldn't heal, you're basically playing a variant wizard and should look at some kind of invoker-like class instead. And if you're playing a cleric of Sune (a love cleric) who can't fight and whose only healing powers are 15 minute long tantric rituals, perhaps you've built a character who shouldn't even be adventuring.
Pathfinder domain abilities (not the spells) have been pretty beefed up, with quite a few giving spell-like abilities to low-level clerics. Air, for instance, lets you zap people with a little bit of lightning at level 1, usually 5-8 times per day, depending on starting Wisdom score. Some of the domains had pretty lame abilities though.
