There are several fine things being done in reaper development. To me the lore breaking and immersion breaking of reaper difficulty are the biggest problem with it. I know many players do not care about that aspect of the game. Many others however do. I like many players began playing DDO because I enjoyed D&D not because I loved video games. The lore of a quest is important to me and the problems of chohesive logic being thrown out the window in some quests by odd monster types cooperating has long bothered me but reaper makes it every quest.
To that end I would like to suggest that the new innovative Champion system changes recently previewed be expanded to include a reaper champion buff package being applied to existing monsters in a given quest rather than spawning these creatures universally in every quest. Thus in water works for example we would see some champion kobolds with champion buffs as previewed but for every 10 monsters one would be spawned with the reaper champion buff package effectively making them a reaper type with the same mechanics. Thus keeping the same or close to the same difficulty that reaper currently has without spoiling the flavor.
