About Fiora's new ult
Let me start by saying this is a huge improvement from her old ult (obviously), and it looks great.
The problem lies with the %max health true damage. Everybody hates to play against this stuff. That's why it is restricted to once every three auto attacks on
. When Fiora activates her ult, she can walk up and instantly proc it because there is a weak spot on every side of the target. And she can likely proc it again right away.
You might say Fiora can only do this when her ult is up, but she will know this. She is able to choose only to go in when her ult is available. It looks like she has plenty of disengage to avoid fighting when it's down.
She now has attack speed, crit, a slow, an on hit application spell, movement speed, true dmg, and %maxhp true dmg as her kit's offense. For defense, she has healing, a dash, and her new, really strong looking Riposte spell.
What should be done for starters is to make her ult deal %current health true damage.
