Well, golems don't rout, ever. They're rather unique in that.
For the PD issue with druids, it depends on what you're facing. The druids spew a ridiculous amount of damage real fast, so the biggest threat to making the PD rout before the druids can lay the smack down is archers - anything else needs to spend a couple rounds closing and a couple rounds killing which is all the time the druids need. If your opponent is fielding significant archers just skip the PD completely as the druids are basically immune to it. A combination of archers and cavalry/flyers is the hardest thing for the druids to handle (pay no attention anyone in my current game), but small numbers can be handled by throwing in a summon earth elemental or swarm before starting in with the evocations. If you're talking about large amounts of cavalry *and* archers...well that sounds like where the golems need to go.
