Says to not speak for people who aren't me, which I didn't do, then proceeds to do that very thing. The number is irrelevant to you. I can't help that you don't get the larger concept of identity in a video game and instead want to pare it to an argument of semantics. The number beside your name is an indicator of who you are, much like the title. When we hit level 100 we will be proud of that accomplishment.
And more to the point, your level doesn't affect gameplay in the slightest. What purpose would the proposed idea serve other than to arbitrarily change numbers? Or are people so naive to think that Blizzard should rebalance the entire game with different npc stat budgets to accomodate what is already 'smoothed out' in the same rate by way of XP needed per level?
Edit: you also don't understand the concept of knowing you have accomplished x level by way of earning y XP. Stats on your gear aren't broken down into x number of dungeons, y number of quests, z number of LFR runs. You pretty much don't understand philosophy in the slightest. But go ahead and eyeroll some more ignorance my way.
