Hello!
As we all know, with each generation you got +30xp to tick. It means, that each next generation will come on 3% faster then previous. Also, we all know, that there is no bonus gold from each generation. It means, that from each generation you got less and less gold, because next generation comes faster and faster. To what I'm leading? To usual, in our days, situation, when someone offer his loompoint to sell for (!) 600k or more. This is ridiculous. Even from 1 generation, if you will use 0 upkeep gear after repair starts, you phisicaly cannot get more then 500k gold. Before you breach this limit, you get on 31 level, and own loompoint comes. And so on.
Now what I suggest: set some dependings from generation of buyer and price from seller on loompoint. And, the higher generation has buyer, the lower price must be. Also, each buyer must add (before transfer) a screenshot with his "Stat" page. We will pretend, they will not edit it in Photoshop. Also, to avoid unfair trade, there must be some minimal limit of loompoint price. Let's say, 300k.
Or, maybe it will be better solution, add some gold enchanser to each generation. Let's say, +5 (+3?) gold per tick.
Sinsere your's.
