新板蓋倫殘血兩秒回滿，Ｅ可以吸血太變態了吧！？ˊ真戰鬥陀螺登場！！！

Looking at the Legacy Cursor as an example: 

• We shipped an update to LoL's cursor in July 2018. Our belief was that the updated version would be a better experience for most players. That generally seemed to be true, testing did indicate that a subset of players indicated they found the cursor change really disruptive though.
• In response to that we added a Legacy Cursor option to allow players to opt into the old functionality. Cost, both upfront and ongoing, of doing so was pretty low and audience asking for the old cursor seemed to be of a meaningful size.
• As with any legacy feature we made a note to reassess at some point, see if it was still worth supporting or no longer necessary.
• Somewhere along the way we got some wires crossed in our internal communication and the need to assess the Legacy Cursor was assumed to instead be a need to remove it a year later. Cursor gets removed, players get understandably sad.
• We then take a look at who's using it, see that it's around 10% of the LoL playerbase, and add it back in. Cost of maintaining it's low and value seems pretty meaningful."
