I can’t really go back. To a great extent, Warhammer’s open world RvR is everything the Ettenmoors wanted to be and is not. It is not greatly difficult to mentally transpose Order and freeps, Destruction and creeps, and see how (shock shock) PvP works out better in a game built for it. Compare the creep Defiler with the Greenskin Shaman: even the names are similar, but the Shaman is a much more fun, viable class. Would you rather play a Reaver or a Marauder? I had more examples here, but I am already losing the people who have not played both games.
One way that The Lord of the Rings Online™ Volume One: Shadows of Angmar™ wins is if you think of creeps as “playing the monsters,” rather than being their own thing. If you just want players being a more realistic AI, where the real market is the freep classes, monsters work brilliantly. They even replicate the PvE mechanics: they have high hit points (and can trait for “ridiculously high”), few abilities, few appearance differences, large numbers, and little resistance to crowd control. They respawn quickly and tend to trickle in at a constant rate, although occasionally you get a huge train. You can easy pull a few, because people will rush out and be easy kills, although you risk pulling the entire zerg if you do that a few times. Healing still draws aggro, although the de-taunt abilities do not work in PvP. Players can capture and defend keeps, but if people wander off, the monsters quickly return things to the “all red” default state. And just like the tutorial, beginning creeps are easy fodder, weaker than all the real players.
You can debate whether that is the intended “monster play” implementation. The NDA for The Lord of the Rings Online™ Volume Two: Mines of Moria™ fell this week, so maybe the PvP changes there are significant. It will take a while for the effects to shake out what with new levels, new gear, across-the-board defenses nerf, etc. How dead with the Moors be for that first month after the expansion releases? (Note to Turbine: the 5-10 page Dev Diaries are really annoying. I don’t want to load a new page every two paragraphs. You don’t have ad revenue, so why are you doing that? I never finished the Runekeeper diary.)
