Sorry if this was already discussed or suggested.
A level 14 randomly generated belt can get 8 strength(and another 8 in a different stat), but the named girdle from gianthold gives 6 strength and two -1 penalties. If it was a similar item in a new adventure pack with power creep in mind, it would have like +8 Strength, Staggering Blow, +2 Insightful Constitution, Set Bonus "We Might Be Giants": Roar, +7 Stunning, +7 Fortitude Saves.
New players that have done their homework won't buy older packs as long as the quests patch up the holes in their xp progression up to epic, just because the items are awful. It's like new adventure pack heroic items are so grossly overpowered just so people will buy them because then they can frolic happily through reaper difficulty much more easily.
Thank you for reading.
