I will now attempt to balance all of the FOTM champs
Lemme know if I missed any.
Add a scaling mana cost to W, lower the healing of her passive.
Lower base and ratio of passive, higher cooldown on ult.
Lower the duration of her ult, less damage on passive.
Nerf BORK. Remove movement speed buff on transformation from mega to mini, lower max health damage on W.
Add a scaling snare duration instead of the stagnant 2 seconds, this gives her more incentive to place points in it. Could even buff the late game by increasing the duration. Something like 1.25 seconds, 1.5, 1.75, 2, 2.25.
Higher cooldown on E and W, less insane passive.
Remove Villain mini game. Seriously, it's stupid as hell. Definitely make Judgement do less damage to minions so he can't clear a wave with one E. Add a resource so he's not the most braindead simple champ in the league. Reduce duration of W at later ranks. Remove the removal of unit collision and once again make garen move slower during judgement through minions.
Give him some actual mana costs, especially on E. Move the heal on Q to W, have it scale with levels. There ya go, now there's a reason to level up W.
Increase mana cost on Q, lower base damage. No one enjoys eating targeted damage every time the Q is off cooldown.
Revert him back to the way he was before you destroyed him with your rework. (Ignore this one, I'm still a bit salty from like two years ago)
Nerf BORK. Increase ult cooldown to 100, scale it down to 60 with levels. Lower Q base damage, start W's mana cost at 50 and scale it up with levels.
Remove W passive, allow W to be cast on minions.
Increase mana cost on Q, but make it so using it on terrain also refunds half the mana, lower base damage on E at later ranks.
Cooldown for Q begins after last use of Q, ult cooldown increased, ult duration lowered to 10 seconds, or when wind slash is cast.
Nerf BORK. Increase cooldown of W, lower base damage of W slightly.
Remove or severely decrease his E's passive damage, remove Q's innate cooldown reduction, allow enemies to destroy or use the lantern.
Nerf BORK, lower attack speed on W, decrease damage on E.
And finally,
Nerf BORK, decrease duration of W, lower bonus AD from ult to 20/35/50 so she actually has to build more than just attack speed.
