Kalimos in Un'Goro... I love Elementals, and the idea of a deck but... they were i guess too slow and there is not that many good sinergy between them... i hope the deck can be good in a future, but yeah Kalimos is just there.
In this expansion... i dont know... i crafted Malfurion (Dont hate me) and Thrall, maybe i could regret making Thrall even if Evolve shaman is tier 2.
I can confirm I also crafted both of the Warlock legendaries in the first few days last Xpac. Basically just an 800 dust bank for the Frozen Throne release, lol. I genuinely believed it was going to work, but yeah, without any sort of discover/discard pile interaction, the archetype is never going to work beyond the Karazahn-esque aggro deck. I also probably didn't need to waste the dust on The Voraxx but at least he was a bit of fun... for a week.
As for this xpac? I actually don't regret any crafts yet. Even Lilian has been a surprising amount of fun in some casual games, which is all I was hoping for with her.
I never craft on day one unless it's a warlock card and even if it ends to be crappy,i dont regret it.However i craft so many cards that i know they are bad because i am itching to play or create a specific deck i have in mind.After satisfying my impulse,i feel bad about myself for wasting a ton of dust :(
Kalimos i mean the card is realy good but elemental shaman sucks
Malfurion the pestilent i dont get it what the heck is so good about this card imo sucks hard but every druid deck uses it so i guess its a must have - only regret in KoTF
Kazakus beacuse when i crafted it i got it the same day in a free pack after i completed the quests
Patches the pirate i know its used in almost every single midrange and aggro deck but its just a stonetusk boar for crying out loud card is not fun or creative its just staple and thats why i dont like its not fancy or cool or interesting its just a must have
I crafted a bunch of legendaries like DK Uther, Archbishop Benedictus, and a few more and while I actually haven't played much with them I don't regret it. I might experiment with them later on, and hell they might be stronger in a later expansion.
