Interesting. Do any of them work directly on the balance team, or are they more focused on obtaining the data and making it accessible?
We have an analyst that works on the summoner's rift team 100%. But what reddit knows as the balance team is actually only 1 of the 3 pods of the summoner's rift team. That analyst services the 3 different pods.
You wouldn't really assign a data scientist to service a particular team, that's too low scope for the type of stuff that they're trying to do. Their job is to make different types of data available for the analysts to have access to all across LoL, whether that's for Skins, Champions, Balance, etc.
