The actual contentious issue at hand, once we strip all the name calling and unproductive text (ie you’re a shill, or you’re a conspiracy nutcase) can actually be tenable from both sides.
Let me concisely put into words what I believe is the issue being argued:
Blizzard may be using information other than a players estimated skill (MMR) in matching players.
In the patent describing their match making algorithm they neither confirm nor deny the above is happening.
So whether you believe the onus of proof is on the side of the Blizzard shills or the conspiracy nut cases is completely dependent on what you believe to be true before you come to the argument rather than any objective fact.
You may think allegations that Blizzard uses information such as what deck you are playing to match you as ridiculous and therefore your stance will be that you require proof before you even consider the possiblity.
Or you may be convinced you keep getting matched against hard counters and therefore in your mind you require proof they are not purposefully matching you against your hard counter.
All that said, I will say there is a financial incentive for Blizzard to match unpaying players against their hard counters in order to spur them into buying the dust needed to play a stronger deck that may have less counters.
Open your mind folks, there’s valid arguments on both sides of this divisive issue.
