As you and [MENTION=996]Tony Vargas[/MENTION] are discussing, you can probably depart (at the risk of player disgruntlement, I guess) - and I think [MENTION=463]S'mon[/MENTION] has departed too. And I in my (still fairly new) Dark Sun game we will be using inherent bonuses, which means probably treasure will be much more haphazard than in my main 4e game.
I'll be using a Moldvay-Cook/Marsh B/X inspired approach in my new 4e Nentir Vale game - low level areas have +1 stuff, mid level have +2 and +3 stuff. No +4 or +5 stuff unless we get into super-high level (16-20) play, and capping level at 20 rather than 30. Heroic Tier PCs could receive gifts of +1 and +2 gear, since that is the level of stuff that is crafted and traded. +3 stuff would generally be legendary, not traded, unlikely to be gifted except in very special circumstances - "Reforge the Sword that was Broken".
For this to work, for a +2 bonus to mean something, no Inherent bonuses of course. I will be encouraging Expertise feats though which give +1 at Heroic & +2 at Paragon. Also will be tending to lowball monster/NPC levels and using minions with 1/4 hp as the 'standard' opponent, 'standard' monsters as leaders & elites. Converting most Elites & Solos down a step.
