While I like the Advanced Campaign, there is some things about it that can be quite "Beardy" so to speak. Here is the list of my beefs and recomended fixes.
1. Outdoor Encounters and Soaring Creatures: These encounters become VERY nasty to copper level PC's. Often times you don't have the kind of range to hit these kinds of creatures and in encounters with an All-Soaring combat force, your melee characters become useless as its easy for the Overlord to run around the melee people twaking the ranged characters and then swarming the melee guys.
Suggested Fix: Soar only applies until the creature makes an attack. As soon as the creature makes an attack, it is assumed to move to ground level. There it remains until the start of the next Overlord's turn. In addition Obsticles are ignored when targeting Soaring Creatures with ranged/magical attacks and you may move under a soaring creature but may not end your move under such a creatures. This makes sence because the creature is high in the air and thus can't claim cover from things below them.
2. Trees and Shadowcloak: Ok, I understand why having tree cover can make you harder to hit. But it dosen't make sence when you're caught in a burst or breath weapon that saturates the tree with a massive area effect. Shadowcloak can be heavely annoying for many combats.
Suggested Fix: The shadowcloak granted by trees does not apply against Breath or Blast attacks that include them in the radius.
3. The Ship encounters are interesting but it dosen't quite give the feel of sea combat. Ships only move in a straight line (unless pulled by the current) and makes it hard to dodge obsticles. One touch on some sandbar and you lose your ship and a whole crudload of VP. And since stearing only moves you sideways, its hard to keep your ship from floating off the edge of the board or crashing. Also makes it hard to aim your cannons.
Suggested Fix: Ships may make a single 90 degree turn a round. To perfom this you must spend two power enhancements on a captianing roll. When turning a ship, rotate it 90 degrees from the center of the ship to line up with the squares on the map. You may not turn if your final position would end your move on a solid obsticle (like an opponet's ship). Any creatures in the water are moved out of the way of the turning ship.
4. Lieutenant "Board Edge Hugging" to avoid being killed.
Suggested Fix: Either require the Overlord to place their Lieutenet in some central area of the board or have some requirement for fleeing (Such as being reduced to half wounds)
