The Great Warden in the Sky Has Answered

Patch 6.13

• A focused patch on the support position, looking at things like support XP, tweaks to a few items that aren’t hitting the mark (e.g. Ruby Sightstone or Forbidden Idol), small buffs to some champs that often go support, etc.

• This is not a large class update like the one we recently did for mages, but instead a collection of small changes we can get out quickly.

• Improvements to how Champion Mastery Grades are calculated for supports.
