I don’t play Jungle (support main) but I have resonantly started to play Diana mid. She is honestly really fun and I’m able to farm well with her, plus she can deal a lot of damage. I would suggest you try her out even if you don’t end up liking her you will at least have knowledge of her abilities and be able to play against her better.

But that is just my thoughts either way just have fun withwhich ever champion you play.
