Good hit effects - Every hit feels good and you can see the chat spamming "nice" whenever damage is dealt, even if it is inconsequential
Shopping simulator - endorphin rush from upgrading gear
Long downtime - can zatsudan with chat or just chill if you don't really want to talk, excuse of focusing on the game and listening for enemies
High "Not My Fault" factor - Even in a perfectly balanced game the chance of winning is 5%; many factors can cause a team to lose ranging from bad loot rng, third-party, miscommunication, aiming 'luck' in 1v1s...difficult to blame chuubas for losing or throwing a match partially also due to low expectations, while getting Champion is amazing and leads to (for JP chuubas at least) a rush of SCs (This is also why chuubas like mahjong - all players being equal you still lose 75% of the time, so it's easy to put losses down to a run of bad luck)
Loot crates - Can make entire streams out of opening loot crates and people will donate for the chuuba to get more
