For optimized Clerics, Extend Spell, Persist Spell, and Divine Metamagic: Persist are often as good as class features. However, a not too rare house rule is to ban Divine Metamagic (due to its extreme power). I've never been in such a game, but it seems obvious to me that this house rule will have major consequences for what Cleric builds are viable. For example, it potentially frees up three feats for you to take. I would like to know more about this. What changes are typically made to Cleric builds when Divine Metamagic is banned?
Note: I'm not asking for Theoretical Optimization builds. After all, if a DM is going to ban Divine Metamagic, then any Theoretical Optimization builds are likely to get hit by Rule 0. Given how common I suspect this house rule to be, I wouldn't be surprised if there's a handbook for it.
