Five bottom lane Champions have been changed in patch 5.9, and though they are small changes, they will shake things up. The short version is basically the following:
Ashe’s rework is now live.
Annie’s basic attack range is reduced by 50.
Kalista’s backward kiting had its range reduced.
Morgana had her early waveclear reduced (unchanged at rank 5, matches pre-nerf numbers at rank 4).
Tristana’s E damage per stack is increased.
