OK, assuming that this is not going to be changed, I recommend building a 28-point cleric and just work your way through the favor. I think there is a thread about the quickest way to get there (I'd look it up, but I'm lazy, and it might have been purged), but if you just work your way through the favor list starting at level one, starting your own groups when necessary (just advertise that you need a guide; clerics never have trouble getting groups), you should have it in no time.
Personally, I have two 28-point builds that I still play; sure, they could be better, and I'm bringing up a replacement for one of them, but I'm not rerolling my cleric![]()
