cause at its core what its trying to do is futile (old but still applicable)
thats just how it tries to determine who would make for a good matchup…then you gotta throw on top of that all the things the matchmaker cannot predict…in particular the stuff that happens AFTER the matches start:
- like who plays what hero
- what comp will be played (OQ especially but even in RQ)
- who uses comms
- who isnt playing and doing something else at same time (child aggro for example)
etc etc etc
all those can have major effects on the game itself even in the most optimally matched game…
basically the game has next to no idea what is going to happen in matches…because it cant…and even if it could it wouldnt matter much once the match itself starts anyway
