Lower Vi mana costs please.
I queue up as jungle primary and mid secondary and I'd say that works well to give me jungle about 80% of the time. However, every time I don't get jungle and am forced to go mid I usually have to play extremely passive and boring during laning phase in order to not feed because she cant lane against hardly anyone competent. A step in the right direction would be to lower mana costs. They are extremely high for no reason really. The jungle items now give so much passive mana sustain that jungle Vi rarely goes OOM anymore, so lowering her mana costs wouldn't really buff her jungle over the top or anything IMO, and shes sitting at 48% win rate anyway. So I think this would be a great way to buff her QOL in lane while not putting her jungle over the top.
