Speaking generally (because I don’t know the specifics of how things work), the QP algorithm seems like it prioritizes maps with lower community-wide success rates rather than your individual rates or being truly random.
Having a higher chance to get a couple maps over others gets old quick (without the odds changing).
I don’t like getting the same map multiples times in a row, and it’s always the same 4 maps being Skittergate, Blightreaper, Enchanter’s Lair & Convocation of Decay.
I used to like playing playing on these maps, but when I get them 3 or 4 times in a row it just hurts to play them.
There are multiple ways of addressing this, the easy answer being to avoid getting the same map twice within X amount of time or make QP truly random.
