HotA has a list of more than a hundred changes for the better compared to SoD.
Next, aside from OH, what is actually so great about HotA?
But in this thread, a SoD vs HotA holy war is pointless. People are leading you to something else, not to furiously defend HotA, but rather:
On HeroesWorld, there are 2 categories of tournaments: official and unofficial. All tournaments held under HotA are unofficial, therefore their value and prestige are significantly inferior to the official tournaments (Lubimchiki, FB, Only-HL, etc.) which are played on the SoD version.
Play whatever your heart desires, SoD or HotA, it doesn't matter, but the value of official tournaments should in any case be many times higher
