I don't. She's too passive and I hate that shit. Give me a support that can actually make things happen over one that just sits in the back. I know it's hard to believe but Janna does have weaknesses and those weaknesses do actually matter. She's definitely too strong on average but she still has the same weaknesses she's always had whether it's a weak laning phase, a weakness to long ranged poke, or a complete lack of initiation or poke of her own. Not to mention all the morons that lock her in expecting freelo and go 0/9 because they're playing like they don't even have to try.
