Full Disclosure: Stonetroll Crossing is one of this writer's favorite scenarios, and definitely his favorite Tier 2 scenario.
Stonetroll Crossing rewards killing other players as well as carrying a "flag" type item to various control points.

Stone Troll Crossing is a 12 vs. 12 scenario in Tier 2 Chaos vs. Empire. Anyone between levels 7 and 23 can hop in this Scenario and duke it out.
This match is pretty straight forward... kill or be killed, but avoid the Trolls! That's right, Trolls. You're fighting on their turf and they're not too keen on either Realm being in the area. Because you're trespassing, our not so friendly Trolls will be hurling large boulders into the area from time to time. These boulders aren't lethal, but they cause a hefty knock-back to both Realms. This throws a bit of variety into the standard team death-match.
When you first enter the scenario you'll be presented with the option to go straight ahead or cut to the right to take an alternate path out of the spawn area. The majority of the play area is lowlands with large boulders breaking up the space, but there is a large tree mound in the middle that has spiraling walk ways up both sides for an elevated fight. Gain the high-ground, and you can do some damage in this Scenario by forcing the enemy to come to you. The disadvantage to being in this elevated position is knock-back vulnerability. Don't get too comfortable on your perch because it's just a matter of time before you'll get knocked off. (Source: Warhammer Herald)
