While it is true that a lot of things that were complained about were nerfed, let’s also remember that there are probably even more than that were complained about that were never nerfed because they didn’t need to be. Duelyst players have bitched about almost every card to appear in top meta decks, specifically ones that people found irritating. As you mentioned there is Makantor and Immolation but there are many more.
Falcius, Mantra, Mana Deathgrip, Desolator. All are cards that people have argued to be nerfed but have not been, and in my opinion this was a healthy decision.
I think that a proper amount of time is needed before people start immediately calling “nerf” less than a week after expansions. This time period is always an absolute shitshow. As @alplod mentioned people are testing all types of crap this week, finding what is effective and what could only ever be a meme. When people pass this stage they will search for effective countermeasures to the very things they found to be effective. At THIS point I believe we can sensibly discuss nerfs or changes.
