I am a little torn on the new Divine Intervention. Literally 2 sessions ago the 10th level party's cleric made a last ditch effort to save a village of 500 people from an attack on all sides. The party knew they could take on the force but didn't think they could save the vilalge, but the cleric hit the number and teleported the whole village away to safety.
Its a story I know will be shared with my group for years to come. So I am loathe to remove that kind of epic once in a blue moon power.
On the other hand, that old version really did require a lot of DM fiat, the new version is clean, easy to use, but still solidly powerful. I could also argue the 20th level version is a bit broken, we have already noted concerns about the sorceror getting the ability to bypass the safeguards of wish, and this does the very same thing.
I think I agree with Titan in potentially allowing both.
I've had a lot of clerics, but actually it was my own cleric that was the only one I've seen attempt to use this feature... and it was during downtime where I spent a month praying every day to bring an NPC back from the dead.
I also have thought about taking the old version and tying it to the Piety system from Theros. This gives two advantages I think, with one of them being that now any pious enough worshipper might occassionally get a miracle, which is very nice for non-cleric pious characters.
