Iron Banner was supposed to make gear and levels matter. It's the reason everyone has been raiding and grinding ascendant shards. Many people and I have been busting ass to get our characters as high level as possible before IB came out. Now, we find out we could have been lv 21 and still done just fine. Crucible already exists for what you speak of. This was supposed to be a simple week-long event where your hard work paid. If a 140 lb man knowingly joined a wrestling match with someone who was 250 lbs, he would lose. That's as good of a metaphor for how IB was supposed to be as any.
