The reasons for Yuumi and Azir changes

Patch 13.5 is highlighted by two major changes to champions, Azir and Yuumi. For Yuumi, this is a long time coming with the playerbase left frustrated at the current state of Yuumi. And while Riot are not one hundred percent certain the changes to Yuumi will resolve their problems, they believe it is a big step in the right direction.

Azir has been in a weird state for some time. In the competitive scene, the mid laner is thriving with its consistent presence across major regions. For soloqueue, however, the results have not been the same. The aim for these changes are to bring Azir back to a balaced state between competitive play and online solo queue.
