I found watching this fascinating, doing some maths autism on the games market again but looking at the searches and comparing it to the steam data makes you think. The keyword searches are probably a fairly accurate gauge of interest in these games because even with botting it's probably going to account for people looking up things like guides for the games and generally searching it up.
As opposed to steam where yes, people will buy the game in question but then it will be dead as anything if you actually log into the multiplayer or you find it's completely broken and there's something deeply suspicious about the reviews.
I agree the overall game is lackluster (also tried when it was free), but if I were to try to sell its strong points, I did like the open world concept, but that was about it.
I do hope they continue to improve it, maybe it will be a good game at some point, but I'm not holding my breath. Right now it's, as you say, very bland.
The problem with it is that it has no idea what it wants to be. Its trying to evoke D2 heavily, but with the simplified playstyle of D3 and an extremely intrusive GAAS model.
And it can't do any of those right, and it won't be able to without stripping out the other 2. At which point they are better off just starting from scratch.
