Expand the lore of Janna
Janna is a powerful mage , the elemental magic of air , but on your lore this is not explored , in its lore is described in an excerpt which Janna may have bipolar disorder or something and it is not shown in game , on future event of Zaun/Piltover Janna probaly don't have utility
In a future event zaun / Piltover probably Janna will not have much use, until the riot actualize its history up to the event, we know Janna is that: it is the elemental magic of air and that she had to do things for their survival as stealing and etc ... I think Riot should go deeper in the lore of Janna, besides her merit an extended and more detailed lore, it also deserves a rework your model in the game, Janna forecast skin improves your look, however not all players that is able to buy this skin.
SORRY FOR MY BAD ENGLISH
The phrase that supposedly describes Janna as bipolar : . There is something untouchable about Janna, however, and her affections can change as quickly as the wind.
