Yeah… the current setup feels like gambling with real money.
What is the reasoning for hiding the new skins behind a random number generator? The only real benefit I can see for ANet is to foster more gems to gold conversion.
On a related note. When will the gem store skins be updated with more options? There are only three armor skins (one for each armor class) with no sign of updates since new skins are being attached to random black lion chest drops.
