Every week there is a 1/6 for each armor piece the week before doesn't not change this, the only way probability changes is if they remove what was chosen from the pool. Since we had multiple armor pieces multiple times in a row this is not true. That being said again there will be a 1/6 chance that it is voidfang again. Go take a prob ans stats class before making yourself sound like an idiot
You never proved me wrong though... I'm asking that if your logic stands then when i flip 100 coins every possible outcome of those coins has a 50% chance of occuring which it does not!
Based on your logic, this is Xur 12th appearance he has sold sunbreakers 3 times (I think) and voidfang 5 times total so 8/12 it's has been either those two armies so there is a 75% he will sell either one of those next week
