Well everyone who works at Bungie is -blam!-ing stupid, Why does the level 41 PoE have matchmaking and the Level 42 one doesn't it makes no sense.
The level 41 is easy as -blam!- and someone who was even under leveled managed to do it but trying to do the Level 42 Challenge of the Elders on your own is more or less impossible.
Can we have matchmaking on all of the PoE even including the older ones like Skolas's Revenge and Machine Wrath

Silly boy, the matchmaking was inside of you all along.
