When I was 6 digit up until mid 5 digit, I'd say most of my playtime was in multi. I loved it because in solo, I was super indecisive on what I wanted to play, so it was great to just have maps picked for me. Also it forced me to not retry spam at all, play one map all the way through, and play tons of different types of maps. I highly recommend it for people who think they retry spam too much, or are too 'perfectionist' in solo play. It doesn't have to be a social thing or something you only do with friends.
