Hey HoneyQT,
I stumbled across your guide on Janna and had to check it out. I've been maining Janna (along with Lulu) some seasons ago and got a bit disappointed when her passive got nerfed from a global effect to a relatively small circle and then again only when allies where walking toward her. However, I never really neglected her, just didn't play her mainly anymore. Recently I saw her in my Collection when I was looking for more champions to play and remembered how great she can be. I always thought that she did't feel quite the same anymore but I was actually wrong. Her W rework is actually quite strong and I just noticed how strong she can be in lane and how much people actually underestimate her.

I used to play Janna with Summon Aery and Resolve, but to be honest, I looked into Arcane Comet with Relentless Hunter and Taste of Blood and I think you should definitely give these runes a try. They're super strong on her. I know, Janna used to be that OP disengage and protection-focused champion, but she can be that plus have even more poke potential, especially with Shard of True Ice. :)

But you've got quite a nice guide for starters. Keep going, I like it. <3

I like Bone Plating mainly in lane, It gives her a lot more survivability as usually Janna is very squishy. It helps in matchups like against a Varus or a Vel'Koz or something that can constantly outpoke you. Your only other options are Conditioning and Second Wind, which don't help her very much IMO.

As for Aery, it's fine and a rune you can definitely pick when Guardian isn't good, but right now Guardian is just better with how much of a shield it gives now that in can proc from a range.
