From my perspective I've already blown all my gold and it takes me a long time to save up enough to upgrade my gems. Now the new loot system sometimes gives me tough gearing decisions. The only way I know how to evaluate the choices is to swap back and forth between those weapons (the main example) and see how things play out.
Currently it's costing me at least 1 million gold to swap a gem into a new weapon for a trial and back again. This serves no purpose to the game.. Just remove the cost please, thanks.
