Guide updated with 25.1.1. Minor changes to runes, Threats&Synergies part updated to include almost every support matchup. Will go in a bit more detail regarding T3 boots once the "dust settles" with balancing them and I have reasonable sample for them.

Guide update (mainly items) after 14.19 drops.

Update coming out with mid season patch (14.10).

Guide will get an update at the start of S14. Don't have access to PBE, so it will probably be out in a day or two after the live patch drops.

Update coming out with next patch (13.10) to include mid-season item updates.
Can't access PBE, so will be behind the release, to have the time properly assess the changes related to Mao.

Update incoming with patch 13.7 release (05/04-06/04).

-Grievous wounds changes (including Thornmail and Oblivion Orb)
-Some new support matchups
-Minor adjustments (taking 13.4 Mao changes into account)
