Tanks rule supreme in the League patch 12.23 complete preview

League of Legends patch 12.23 is shaping up to be a huge one, as Riot Games plans to make significant changes to preseason 13. This is League’s second preseason update, and it is likely to include a variety of tweaks to jungling as well as big buffs and adjustments to some underwhelming champions.

It is crucial to remember that the changes indicated below are still early. Riot Games will first test them on the PBE server before releasing them with the patch 12.23 final release. The following is a summary of all the expected changes in League of Legends patch 12.23.
