Well, i'm not really sure what move is not noob nowadays, but first of all I don't understand why DMs(especially decaps) are considered as the deadliest of sins, and a noob certificate. Do not you remember the first time, when you finally managed to rip this head of his shoulders? Was it satisfying? Hell yes! But after all - it was skill demanding. Of course, a newbie can also randomly dm, or even decap his opponent, but situations like this are pretty rare.
