I did a little of everything - I primarily worked on the Dungeon system, but I had a hand in monster, class, rewards and PvP design as well.
Can you explain the Janna nerf? As an AP Janna player, I have to say I'm pretty upset. Are you trying to say Janna is played as an AP mid too often? From what I've seen, she's more of a niche pick.
AP Janna is honestly very fun to play, and I really do hope you'll reconsider nerfing her ratios. (as a side note, the nerf to Janna's W isn't going to have a huge impact on Support Janna, so why nerf it in the first place?) Is there something we're missing in the patch notes?
