Testing and experimenting with the new WoW level scaling system, and seeing how it impacts enemies, gear drops etc. I'm wondering if this is something that WoW players would actually embrace, to the point where they whole game could be focused around it?
Concept:
Because of the way the scaling system works, this would mean that players would always fight enemies of the same level, gain xp, slowly level up, which will make the scaling system make their gear slightly worse from being scaled down. But enemy drops will always scale to your level, so new drops will be higher level and thus give better stats.
This will keep the loot/gear thread-mill working by itself, without the need to interact or make new gear.
In order to make a system like this work, with expansion packs and new content. The game would need another system in order to mark “progression” to qualify for next story/expansion etc.
A “Rank” system, that you gain ranks from doing story/expansion content would allow for this, even if it isn't terribly original or interesting.
A similar system could also be used for Dungeons/Raids if wanted, so people have to go through them in mostly order, and progress through them upward.
Cons/Pros: (Depends on Perspective)
