Janna is currently ranked in the A Tier for the Support role in Patch 16.2.1. This tier placement is based on a solid 6.2% pick rate and her performance in Platinum+ ranked games. She remains a strong and reliable pick for players in the current meta.

Janna's overall win rate as a Support is 49.4% based on 2,999 games analyzed in Patch 16.2.1. However, when using her optimal builds, her win rate increases to 51.0%. This highlights the importance of following the recommended itemization to maximize her effectiveness.

While the data is sourced from Platinum+ games where she has a 49.4% win rate, Janna's A Tier status suggests she is a viable pick across various skill levels. Her 7/10 difficulty rating means she requires some practice to master her utility effectively. In lower ranks, her strong defensive capabilities can be a significant asset to any team.

With an A Tier ranking and a 6.2% pick rate, Janna is a worthwhile champion to main for players who enjoy the enchanter role. She has a carry score of 6.1/10, showing she can have a major impact on the outcome of a game. Her build-specific win rate of 51.0% further proves her potential when played with the correct setup.

Janna's win rate of 49.4% is quite stable, sitting just below the average mark. There were no champion or item changes in Patch 16.2.1 that directly affected her performance. Her win rate is likely influenced by her 7/10 difficulty and her effectiveness in specific matchups like Nami.

Ardent Censer is the best first item for Janna, boasting a 54.5% win rate when rushed. It provides essential stats that benefit her shielding and her team's offensive output early in the game. Only 3.7% of players currently pick it first, but its high success rate makes it a powerful choice.

Janna is a particularly strong pick when you are facing Nami, against whom she maintains a 54.3% win rate. Her A Tier status makes her a versatile choice for most team compositions needing peel and utility. She excels in games where her ability to disengage can protect her allies from aggressive enemy divers.

Janna's power spike occurs early when she begins maxing her W and completes Ardent Censer. The W > E > Q skill order is highly effective, yielding a 75.0% win rate by emphasizing lane pressure and poke. During this time, you should play aggressively with your W to secure lane priority.

Janna is strong throughout the game, but her late game is specifically enhanced by the Gathering Storm rune. Her early game is very potent if you follow the W-max skill order and rush Ardent Censer for a 54.5% win rate. Her build-specific win rate of 51.0% ensures she remains a relevant threat in the mid and late game stages.

Janna received no changes in Patch 16.2.1, meaning she was neither buffed nor nerfed. Furthermore, there were no changes to her core items during this patch cycle. Her current standing in the meta remains consistent with the previous update.

The data suggests that the Summon Aery setup with Sorcery and Resolve is the most effective and popular choice, with a 51.9% win rate. This setup including Manaflow Band, Celerity, and Revitalize is well-rounded for most situations. There is no specific evidence in the current patch data to suggest that varying these runes is necessary for different matchups.
