Actually, I'm gonna do the same. Why keep cards I will never play, because I am missing 95% of the wild cards ? Rather disenchant them and play standart with almost all the cards.
U do u mate. All i am saying that wild is similar to regular play. Odd warlock and Kingsbane rogue are kinda there and i have a pieces to not disenchatnt cards for it. Also go and see meta in wild on some site before u decide to do so. Well this is just in general advice. Not nececary to u alone.
Your choice and enjoy the dust. I did the same and hated my decision, and have gradually restored my wild collection. I was sure I'd never play wild but now it's all I play.
Standard will be fresh for the next week or so but once the meta has settled people will whine about a repetitive experience again - as always. And with a smaller card pool there is less room for experimentation.
You also crippled yourself with the upcoming PvE content. If I where you I would have completed that with your wild cards and then dusted them - if you intent to play it that is.
Lul, RIP collection, RIP taverns brawl, Wild is the place, insane combos, great fun. You just commited yourself to perma Standard wher the meta is the same for 4 consecutive months. If i wanted to play a standarized game i would go Magic which developers actuallly care about balance.
