I think traditional supports should be more interactive and have more agency over the game like
does. She has two forms of CC (slow and root), a shield, and the ability to kill things, do damage, and be active in lane (her passive). This change is good across the board, although the numbers are too high to start with. I'd cut the additional magic damage to 1/3 of that value and make the main benefit of applying
's passive so that she has to interact in that exchange for the maximum damage output.
's last changes were a good idea to give her more interactive gameplay so that good and bad Janna's could shine a little better, and further changes to the support role to give it more agency over the game, while also still being low-gold income & utility-based picks is something League of Legends needs going into the future.
