Has anyone ever actually played (or seen someone else play) a cleric with a poor melee build (light or no armour, low Strength score, etc.) that still held its own against the wizard? With some people saying that the spell lists are par and others denying it, it would be nice to get some evidence from actual play.
I think that this is a tough comparison. Clerics need to invest minimal effort to have limited melee ability and it would be odd to deliberately remove this. Furthermore, some elements of the build can make a big difference (what domains does the cleric have, for example, and are they able to cast domain spells spontaneously via feats). Finally. whether the cleric is using spontaneous cure spells to heal the party (and thus reducing firepower) is also a factor . . .
