Because there is a "no duplicate" legendary rule, you can't open a legendary you already own, also classic set is always around and cards get good or bad sometimes depending on meta.
^Yup.
@ OP
First of all, welcome to hearthstone, outofcards and congratulations for the legendaries you have recently opened. Like others have said, those are really good and even though they aren't used in current high-tier decks, they are bound to see a lot of play in the future. Anyway if you have further questions regarding the power-level of some cards, I would advise you to check some "Legendary Tier Crafting Guides" such as these ones:
or you can also ask people in the appropriate threads. I had a friend of mine, who disenchanted most of his starter collection in the past to craft a zoolock deck. I don't really recommend doing the same thing, but some people want to obtain a viable decklist as soon as possible, so that they can farm wins on the ladder, obtain gold and buy packs, in order to improve their collection. So that could be a consideration, you just have to tell us what you are looking forward to do in-game.
Speaking of buying packs, I would highly recommend you to play arena. You will learn how to play hearthstone w/o stumbling upon refined decks with your basic cards and if you manage to get a lot of wins, you will be greatly rewarded.
