Not a negative forum post will scare the new players.
I bet, half of them not even know (or care about) game forums.
They got scared because they have to win at least 5 online matches in a game, they never played before, to gain acces to the TRAINING mode!
They got scared because there is almost 10 level grinding between two levels of the same campaign, and those 10 levels not even enough to manage a certain character, with a proper gun, or cards.
They got scared because a high level character costs 180000 gold, while they spent already 12000-60000 on weapons, exp buffs and card shuffleing,(before they even know, what that character will be cost, because they lock all of the characters info behind level requirements...) while the medium prize for a succesful adventure is 1000g.
It is a world of fortnite, overwatch and other games,that give you prizes, if you just farted before your pc. A game of mass blind grinding will scare them away.
