Without naming Diablo 4 Gold, they record most of the complaints that gamers have against that upcoming project, including the way that it is not being developed by Blizzard, but was farmed out to a third party, and how it's a watered down version of the game on PC.
Years before, the idea of porting Diablo 3 on a phone would have been a bit too intense, however with the rising ability of smart phones, the recognized notion of playing less powerful hardware with the successful Nintendo Shift port, as well as the visuals of Diablo IV which we've seen up to now, this is no longer the situation.
Not porting Diablo 3 to mobiles is a missed opportunity, especially because cross progression between platforms might have been a significant selling point not just for those who still play with the sport, but to lure players to buy it for the first time on PC or games console. Imagine using a full fledged Diablo 3 match and knowing that progress made counted towards a Journey.
Beyond this, the situation for Diablo 3 being ported to mobile devices could be made because in many ways that the sport is already such a simplified sequel compared to Diablo 2 or Path of Exile. There is little in terms of decision making for gear and best end game builds, and when Path of Exile can accommodate its system of complicated character customization, there is no reason for Diablo 3 to not operate as well.
We've not yet seen exactly how Blizzard will want to monetize Varshan admissions, though speculation is that tools for playtime is going to probably be gated, or that one course will be liberated and classes have to be bought. It is hard to say whether a port of Diablo 3 would be profitable, but there isn't any doubt that it would be better for players, particularly people who enjoy the game in their PCs and console.
