A data-driven breakdown of Janna Support for patch 16.17: the most-played and highest-win-rate builds and runes, the matchups that beat Janna, synergy partners, and how Janna closes games — all from ranked Emerald+ data.
Janna is an enchanter in the support, and on patch 16.17 they grade out as a top-tier pick — a 53.0% win rate, 3.9% pick rate, 45,538 ranked games sampled. On the power curve, Janna is a scaling champion: comparatively weak early, but one of the strongest picks on the map once core items come online — so the plan is to survive the laning phase and take the game over late.
How Janna wins: peeling and disengaging to grind out the extended fight, and grouped 5-v-5 teamfights, where Janna tips the fight. The kit grades 10/10 disengage, 7/10 teamfighting. Play around where Janna is thin, roaming and engage (3/10, 1/10), and the enemy loses their angle.
The most-played core build is Dream Maker, Moonstone Renewer, Redemption, which holds a 48.3% win rate across 4,289 games this patch. The build above re-optimizes once you lock in the enemy composition.
The matchup to respect is Zyra, where Janna sits at just 44.8%, the lane swings the other way into Shen (62.4%), and on the team side, Janna gains the most from a Poppy (+9.9% pair win rate).
