Yep these Janna changes officially make no sense
Base AD lowered from 49 to 46 Base HP increased from 500 to 525 Attack Speed per level increased from 2.61 to 2.95 Base movespeed reverted from 320 to 335 AD per level lowered from 2 to 1.5 Zephyr (W) Cooldown lowered from 14/12.5/11/9.5/8 to 12/11/10/9/8 Bonus movement speed increased from 5/8/11/14/17% to 6/7/8/9/10%
You nerf her base AD and give her a shitty magic damage passive scaling off her MS but she'll do less damage and be squisher. Good job.
