I spent all the motes of light i have earned since release just now on xur. Bought the exotic helm engram, thought "yes this fu**er has no chance of giving me a blue or purple from this!!" I only had 1 exotic helm for a titan. So it's for any... ANY exotic helm on the darn game, what are the chances of getting the only one you (I) have? I DON'T KNOW BUT I SURE AS HEL* GOT THE ONLY EXOTIC HELM I HAVE FROM AN ENGRAM... and for the naysayers who will not believe me, I took a screen shot for proof. Msg SteezyGuy21 for a good laugh at my luck. Please someone tell me the chances of this bs... please
