Fioras ultimate makes no sense for a duelist and her w cd is a little ridiculous

I'm a platinum fiora main and have been maining her since early season 3. I really love the way she plays and was looking forward to her rework for quite some time. I really feel like her ult needed to be changed but this was not the way to do it. Yes her ulti was low counterplay bs and yes it did do way too much damage. However i really feel like what they have done with her is not the way to do it. I like her new w alot i fantasized about being able to riposte skill shots and cc it was everything i could have ever wanted but her new w. The cd on it is so long a whopping 24 seconds thats great if she actually STUNS someone or reflects a massive damage skill/ability however with little aas the cooldown is kind of bs. Fioras new q is amazing and her e I'm a little on the fence about i like it but i like the old one more. Her passive is completely rng based and was a good idea but the lack of consistency is going to give her a rough time. But im not here to talk about all that cause i easily could rant on forever and ever about it so lets get to the point her ulti. I really think it makes no sense thematically for a duelist to heal her team what they should have done is keep the expose weakness on all 4 sides mechanic but make it so while shes in the aoe circle she gets a decent ms buff and a very small as buff say 30/40/50% with each of her attacks on a vital point doing a micro stun on the enemy like a .2 sec stun just enough to help her reposition and kind of stop the enemy the overall cc if she can land all 4 would be meh cc and it would help her team be able to follow up. it would give her some really nice dueling potential and still give her utility for the team. I really really really love having a duelist in the game as sort of a anti all in champion but i feel like the healing on her ulti makes absolutely no sense and i wish it was changed to pretty much anything else.
