If you sorted out the butchered grammar and theft of German, you'll find that what I was trying to say, before being captivated by alliteration, is that Tesh sent a tweet that said the following:
"There's something deeply ironic in players whining that #WoW is too easy, but they want challenge handed to them on a golden platter."
Challenge is not in a vacuum, nor is it desired as such.
First off, players may not want challenges as much as they want things that other people will fail at. These serve the dual purposes of sorting and superiority mechanisms. They assist people in forming tribes and feeling superior to the people in the other tribes.
Second, they may want challenges, but they want challenges that they can brag about. This is when obscurity and balance come into play. First off, the challenge cannot be obscure. Imagine trying to brag about something in a game to somehow who has never played a videogame before. See how the audience needs context and a sense of the scale of the challenge? So saying "I soloed X" piece of content, if few people have done that content, or only did it at much higher levels, or anything else that would prevent them from recognizing the challenge and how it has been overcome, with be ineffective.
Balance matters as well. If I beat the challenge and so did you, then we should each be above the same benchmark of performance. If I beat it and you don't, it means I am above and you are below. Imagine if the challenge was not balance, so that my paladin can beat the supposed challenge with ease, while your hunter has to be played perfectly to beat it. Now the challenge is non-existent for me, while for you it is hard to brag about, because for any non-hunter, it seems trivial. Sometimes there can be a "as a hunter" modifier, but those are not perfect. Then there is the scenario in which it is hard for a paladin and harder for a hunter, so in theory both of us can brag, but I can't brag around you because of the imbalance.
Then there is the issue of whether it is even worth trying. This is a progression problem. I could seek out challenges on my own. So I go out and as a level 20 I decide to solo Ulduman. It won't work, no matter how awesome I am. When can I come back and expect a challenge? Am I supposed to come back every couple levels and bash my head against the wall until I have beaten it? When I cannot yet beat it, do I need more practice or more levels? Notice how none of that was about challenge itself, instead the activity described was merely frustrating repetitive failure, with a high possibility of the impossibility of success.
Maybe I could construct challenge more easily, or maybe conveniently is the better word, by leveling up to where I need to be (oops, how am I determining this? I guess I'll be lazy and try quest color), and then taking off gear, retrying each time I succeed, until I fail, at which point I will define one piece of gear higher to be the point of challenge. That sounds like a pretty stupid idea to me.
There's nothing contradictory about wanting challenge "handed to you on a silver platter." It is sensible. It is a way of knowing if an activity can be expected to be challenging and therefore worth doing for the challenge-seeker, or whether it should be bypassed. Being directed to the challenges does not remove challenge derived from the search, since there is none, only time-wasting repetition that gets in the way of the desired content: challenge.
So in fact the true contradiction is Tesh's, with his dislike of time-wasting, pointless content gates, and his apparent belief that we're supposed to be wandering the world hoping to stumble across a challenge, without any "silver platters."
Finally, beside all that, if a game is meant to be challenging, it is my assumption, and probably that of most gamers, that it will readily provide challenge, rather than an amalgam of NPCs, mechanics, levels, and loot, which will, under certain circumstances and when combined in certain ways, yield a challenge. That would be like if TOR marketed itself a story-driven MMO, and then turned out to be a reskin of SWG, a sandbox, and we were told "go find your own stories!" Actually that could work, so maybe I picked a bad example. How about a box of scissors that you need a pair of scissors to open? Even worse, and totally non-analogous, but I like the imagery.
