Might have more luck in the cleric forum, but here's my opinion on this:
This kind of build is tricky, mostly due to the lack of feats. I actually have such a build, it's an Elf Cleric 17/Ranger 2/Wizard 1 (currently at 13th level). Unfortunately you must be Elf to get Arcane Archer (disclaimer: I'm clueless about Half-Elf, maybe they get it too -- EDIT: someone told me Half-Elves could go AA as well), because AA is a must to have decent ranged DPS, so you can't take advantage of the Human bonus feat. My feats are:
Weapon Focus / PBS / Empower Heal / Quicken / Manyshot / IC / PS / IPS
and I don't see how I could live without one of these... this build was made before Zen Archery was added, so I didn't have to worry about it, but even if I were to re-do it now, I'd probably still do the same and go Dex-based instead of Wis-based (saves the feat and higher to-hit -- my offensive spells will suck anyway with only 17 levels of Cleric, no spell pen and no maximize).
Prepare for people to believe you are totally clueless when they see your build too
So far the build's been ok, although it's definitely less powerful than a normal cleric at mid-levels due to the lack of offensive spellpower. I'm looking forward to the higher level AA goodies.
I would
NOT recommend this for a new player.
