Since funcom went into the token madness might as well go all the way and make almost everything purchasable by tokens.However not by rares.

For example jade dugout should award you 1 jade HM kill token per run,then set a price of items dropping in there for said tokens and be able to buy it.This way you don't dodge the content for something easier and you get that last elusive piece.

Personally i've done jade more times than i care to remember.I got t4 hox belt before seeing the BB belt dropping from jade and my hox is not my main raiding toon so i can understand the frustration of hunting an item in there forever and never see it drop.

Finally some items should remain "drop only" to keep the competitiveness around them,the element of surprise etc on some loot in the game
