It is to me. I think every DJ should learn traditional beatmatching before delving into something like Live.
Learn the basics: beatmatching, phrasematching, keymatching. Then go crazy.
Live is great for multiple tracks, samples, and live beats. It's extremely useful if you want to edit tracks, sample tracks, and create tracks. But for someone new, who wants to learn two-deck mixing, it's overpowered, over complicated, time consuming, and eliminates a fundamental element of DJing. IMO, it's more suited to a Live PA.
