I hear what you are saying. You make a good point about justifying this style and level of loot being somewhat appropriate for the level range - although it is in need of some serious tweaking.
My argument for this entire 3BC pack is that it does not matter. Players do not hover around level 24-25. They are doing VoN 3, EH/EE quests worth 50-100k+ a pop and will not be around this level range for long. Why? Thunderholme, ETR, end-game quests and loot that far surpasses this sub-par offering. We have a plethora of content available to us at this level range and we certainly do not need more quests to flesh out this level range.
Turbine has set the hard ceiling at Level 30. End-game needs to be expanded. We need content at levels 28-30 to keep players interested as they grind away their lives. Putting on level 24-25 loot items for a week or so seems pointless to me. The juice is not worth the squeeze while I am grinding my way towards cap.
