If someone actually read my NM and item drop idea, it actually benefits both hardcore and casual gamers.

Hardcore: Long NM Spawns / Gear Drops more valuable and usable for wider level range.
Casual: Short NM Spawns / Gear Drops usable for a <10 level range.

Of course what I mean by the hardcore gear is that the gear will have extremely nice stats for that level and may still benefit even at Rank 50.
