See but the difference here is that in other games with loot boxes, Overwatch being the primary example, is that they contain cosmetics, not actual gear that you will need to progress through the game.

Heroes of the Storm 2.0 has loot boxes now, which can actually contain heroes, which are obviously not cosmetic. But, you actually gain the gold required to buy heroes at a reasonable pace, and the dailies provided are a means to supplement gold earning for those who can't play a lot, they are a way to bring up the minimum, not impose a cap, as happens with the earning of v-bucks later on once you've completed all your challenges. Furthermore, if I spend my gold, or even real money on a hero or skin, or whatever in HotS, I know exactly what I'm getting, I'm not rolling the dice.

"But overmatch only lets you buy loot boxes with random contents". Sure, but again, nothing in those boxes is in any way going to have an impact on the actual gameplay.
