hello i’d apreciate if anyone can give me answers about this topic.
i’ve already bought the first 10 pack of every expansione (except those going out of standard in april) to get the legendary
now i dont know if get the legendary from the going out of rotation pack, buy classic pack, buy current expansion pack or just save gold and wait april.
thank you for you answers 
don’t waste your money on this pile of garbage
I’m not sure on how the legendary works for the first 10 packs.
There is a mini set being released very soon (I think) it may be worth holding fire on opening the packs until that set has landed.
Currently, it is hard to give an advice, since:
- there will be a rotation in early April
- it seems we will get a rework of Classic set in April
Anyway, I think it would be good to save 2000 gold to buy the miniset (January 21 if the leak is correct about it), of course depending on what cards are there actually - especially those expected 4 legendaries.
After that, I think the best would be to save the gold till April, or maybe limit it to one or two current packs/week and save the rest. Depends also on your game situation: have you progressed from the apprentice ranks? Do you enjoy constructed/duels/battlegrounds? For constructed/duels, you probably need to buy recent expansions to be able to build/unlock duel things.
Definitely get the legendary from the rotating sets as well. Worst case is you would’ve made 1200 dust (+ other cards) towards cards you want and that’s if you get bad cards.
After that check to see if there’s any commons you want from the standard sets and get those packs till you get them. After that save up and see with the possibility of going back to get some rares if the new set isn’t your thing.
If this is true - WOW - such good value. Lets hope Blizzard is really focusing on making cards more affordable. This would be such a good move for the player base and distributing the new cards to all players at an affordable price.
Lets hope an official announcement comes out soon.
