Hmm what about adding an option of "unlooming" items? Possibility to make from +3 item a +2 item and loompoint(and so on)? That's a serious move, because it'd add great flexibility to the market, which would change things drastically. I think it'd decrease value of loompoint to more stable level, and possibly it'd slowly go down alongside with more and more retired chars. But I'm not sure about this completely...
Also, if 'unlooming" had come true, an option to "unloom" item not to loompoint, but to money, would give devs power to adjust prices(in some range) on market by setting a value of loompoint(I wonder how chadz would set that...) - and by that the prices of already loomed items(generally about 400k for l-point would be appropriate, because of money one can gain in one gen, which varies around 400k depends on lvl) . But that kind of "central planning" together with easy unlooming would totally kill trading as it is today.
Sooo, well.. free market with different prices, inflation etc. or dull but stable controlled market.
I suppose my idea had been proposed many times earlier...
