I would like to know what a more granular tolerance actually means. The other major
thing that concerns me is why does Pandora have an ELO-Based matchmaking?
Shouldn’t the win-lose-ratio for each run be the only thing that determines
matchmaking in Pandora? Regardless of the game mode playing better than the average
player should result in above average rewards. This is true for ladder as you
climb ranks until you reach a win rate slightly below 50% resulting in a reward
that’s in correlation to the skill and effort you put in. However, when you
base the Pandora matchmaking on ELO your average win rate and therefor reward will
be the same whether you play at 500 ELO or 2000 ELO. Improving your skill and
putting more effort into Pandora only minorly increases your rewards which discourages
player to improve. In addition, the quality of your Pandora run is way more
luck (cards you open and draw) than skill dependent.
Based on the feedback that we received from you, we are also updating the matchmaking algorithm for Pandora to create a MMR-like score per run, based on your number of Wins and Losses.
Other lesser factors do include a general skill rating, but what the update on December 8th did was increase tolerance in such a way that, in times of low queue population periods, allows more matches to take place so no one is waiting 20 minutes for a match, which was a rare but real issue before this update.
