I haven't played through Elmshore without the level sync, so I don't know if it's the same number of mobs as it is with scaling on. But it's definitely more mobs in 3 of the pulls there in 3.0 with scaling than there was in 2.0 without it.
The Ogre's outside the Ogre bounty cave are the biggest example. Before, those dudes were like a slightly scaled down version of the bounty fight. Now, they're like two of the bounty fight at the same time.
When I first played PoE, that Ogre bounty fight and the Ogres/Ogre Druids on the 3rd level of the Endless Paths were among the toughest fights I had, UNTIL ... I learned that the key to taking down Ogres easily was mind control/affecting spells that targeted Will, such as Confusion, Charm, or Dominate. Anything that will get the Ogres fighting each other.
Remember to have your party NOT target the Ogre you're about to charm. (Don't want to charm him and then void the spell in the next instant because you hit him with a stray arrow.) And don't target the charmed Ogre after he's charmed, at least until he's the only Ogre left to deal with.
Ogres fighting Ogres mean that they're working for you. Even the ones you don't charm, if they're pounding on charmed ones, they're still working for you, when you think about it. Ogres fighting ogres is a no lose situation!
