Janna Fix
Lets be real, Janna is kind of garbage right now, along with a few other Enchanters, but this post is about Janna, not them.
With a 19 second cooldown at first rank, and only shielding for .75 seconds before diminishing over 4 seconds, Janna's once strongest tool has been turned into the worst shield in the game, in comparison to other supports capable of shielding. However, the nerfs were SOMEWHAT called for because it was ridiculously strong. Unfortunately, they went to far, and this has made her fall so far, and while she has always been more of a late game champion, her early game has essentially been gutted, leaving it honestly not worth picking her.
I have 2 ideas;
Idea 1: Simply change up her passive, giving her bonus heal and shield power based on movement speed, instead of gaining bonus damage. Janna is an Enchanter, damage is the last of her concerns, and something that isn't necessarly important in her kit. With an easy to spam W, that on its own deals good enough damage, extra damage was completely uncalled for. By giving her bonus heal and shield power instead, it could possibly open up the options for new, different builds for Janna players, instead of going the same default Enchanter build.
Idea 2: This one is easier to implement, and honestly just a small buff. Decrease the cooldown of her shield at early ranks, while giving a small increase to the base shield amount at each rank.
Damage is just ridiculous at this point of the game, and it has made some of my favorite champions, Enchanters, become almost obsolete, and more of a liability instead of a strength to their team.
