Of course, when dealing with Rush Recklessly, unless you're using it on your turn in your hand, then that's the only time your going to get real speed out of it. But nine times out of ten, your going to be setting it, and getting the same speed out of it you would with a trap. Although, personally, I feel the same way about the notion that traps are slow as I do about the 1 for 1 concept. 1 for 1 only works in your favor when card advantage depends on card count. And how often does that happen? The next few duels you win or loose, take a look at the number of cards in hand and tell me if the guy with the most cards is the one who consistently wins. On the same note, I can't really call a card slow because I had to wait till just after my End Phase to activate it. I also have a hard time calling anything Spell Speed 2 or higher, slow.
Rush recklessly is great, but a 1500 quick boost is nothing to sneeze at, and rightly shouldn't be free of charge. Not to mention, if your set up right, then a discard isn't going to mean much, especially is you were planning on putting that card in the Graveyard to begin with. The thing about it is, people tend to look at a card from only one strategic point of view. A strange melding of economy and aggression. People want the big beatsteaks, but they don't want to pay for them. So there's a tendency to disregard the cards that fall in the middle ground or outside it.
You have to remember, that's the CC mentality at work. There's far more strategy to this game then in just the free stuff. Heck, only two years ago rush recklessly wasn't even in most decks. Most people didn't even know what it was, and everyone and their mother ran United We Stand, a card that sees little play today. You have to think outside the box every once in a while, otherwise you end up just playing the same stagnant stuff everyone else plays, and in a few months, you find yourself starting a thread in the Intro/Farewell section saying your quitting the game because it's gotten boring.
Sadly, all it ever takes for any card to become popular is for one guy to take it to the top 8 at the next Shonen Jump. Then naturally, everyone will assume that it MUST be a good card if the winning player plays it. Which makes about as much sense as saying Nike is what made Micheal Jordan a good basketball player.
