He submits proof with the video. You don't seem to understand the concept of supporting your argument with evidence...

He submits proof that his assumptions about the event are incorrect. He says it is "bullshit", expressing his dislike. He (along with most of us) made the assumption that the gear would have a larger impact than it currently does. All "evidence" that he shows, is just showing that his assumptions were incorrect. The Iron Banner does reward players with better gear, as you would notice from all of the Ceros and Vex complaints. Those guns absolutely tear stuff up in IB. It just isn't as absolute as people believed it would be.

You're talking about 2 guns that are vastly superior in Crucible as well. That's a different discussion. They said Iron Banner was a game mode where all level balancing was disabled. That suggests that higher levels take more damage and deal more damage.That suggests that a fully upgraded legendary or exotic should be more more powerful than a common or rare. That isn't the case. This video proves it. Other videos prove it. What proof do you have other than saying that you don't agree?

I am not disagreeing with you that we all had false assumptions (based on Bungie's comments), but there IS a difference between IB and non IB. Your gear DOES matter, just not as much as we were expecting.
