Actually, the whole point of rigging is that a better player doesn’t use this ‘unfair’ advantage, colloquially referred to as skill 
, and win more, since it would get those player masses FRUSTRATED, as this forum demonstrates.
People believing HS would be designed fairly are no different to me than those who claim that so-called ‘professional wrestling’ is competitive sport comprising matches that are definitely not staged or rigged (which has been more or less the ‘trade secret’ of this whole shebang’s commercial success and popularity, from what I’ve heard) — especially given that some technology with obvious rigging applications has been implemented within the game and demonstrated to the public: Optimotron, Zephrys… maybe there are some other obvious examples, but I can’t readily think of them. You wouldn’t really think a company such as Blizzard, known for its… ahem… ‘generosity’, would design this just so that players could have some fun for free in a Tavern Brawl, would you?
Nice ‘shilling’ for the company!
I knew a HS streamer who used to basically make a living from streaming HS (since closed Beta, if memory serves) for his local community, which included farming the Arena, at which he’d been quite good and consistent. Despite his ability to essentially farm packs for free, he admitted that at a certain point it was no longer enough and he was forced to spend real money in order to stay competetive and have a shot at Legend, then dropped it all since it was no longer financially viable, having subsequently returned only for Battlegrounds (oops, they are P2W now, too, by the way, but that’s another matter). This is just an example of how ‘more’ F2P-friendly HS has become over the yeards — yet here comes a ‘white knight’ with a ridiculous tirade how fair and generous the game is… Go on, tell us also how there’s ‘no evidence’ 
of rigging and so on.
