the prison of elders in not a challenge as much is it a test of patience with the level advantages becoming more of a problem with each DLC being a light level 34 guarantees you to be at a 33% damage reduction against a 35 being a light level 33 guarantees you to be at a 66% damage reduction against a 35 being a light level 32 guerentees you to be at a 100% damage reduction against a 35(bungie hates you basically) the enemies in the prison of elders seems to have double if not thriple the health of normal teir 1 and 2 enemies as well? this can be show if you play POE level 28 and match them at 28 with older gear you can do a considerable and well balanced amount of damage with a great amount of challenge in between but when it comes to higher levels balance is thrown out the window!
