It is sad honestly that threads like this miss the forest for the trees. Is TurboHud a problem? Yes. But is it the problem plaguing the Diablo franchise? No.
The problem is botting. Before the botting apologists say “Oh just don’t look at leaderboards and okay your game” - this isn’t the point.
Bots are primarily used in D3 to farm bounty mats on secondary accounts that are bought from players (for cheap) who quit the game. You buy an account cheap say for 10 bucks then you get it to a stage where it can farm (you can use multiple accounts to make it faster) thousands of bounties. Often the botter will have a separate main account that then gets invited to those games by the bots for free T16 bounty mats say every 10 minutes or so.
As good as infinite rerolls in the cube is the goal. Ever wonder how some of those guys are - season after season - simply the most lucky when it comes to loot drops? Wonder no more. This process is called “cookies” depending on the region you play.
If botting is going to be combatted it must be combatted in its most insidious forms - not just the obvious botters seen on Leaderboards but the many many more facilitating the play of a large portion of Diablo players.
