Diana Rework Idea
Now to start this off. I understand Diana is a mage assassin type play style that is extreme feast or famine atm. What I am suggesting is completely removing her from that type of role and making her into a support to duel vs her sister. Now you can be like well the lore, but lets be honest here riot don't care about the lore anymore anyway. I feel this would give Diana more of a identity in league and make her a different type of fighting support then leona is.
The concept is similar to leona, but she is more moon powered based. Both are tanky fighting supports that have ways to gap close onto enemies to lock them down. Imo I think Diana should be a little more supportive to her allows also though. I also want Diana to hold a Shield now plus her crescent moon blade. I think a Moon shield would fit her perfectly.
Passive: I haven't really thought to much on this something like leona sunlight, but call it moonlight instead.
Q: I actually want to keep this the same as it is, but add a extra function to it. Basically the q will do the crescent out moon pattern it does now, but if you hit a target Diana can teleport to any target with moonlight on them. This is how she will be able to engage and she can pick and choose targets to jump too.
W: I want this to be a aoe shield for herself and allies. This is where she will be more supportive, then leona cause she lacks as much CC as she does.
E: Pretty much the same as it is now, maybe add a slow onto it. But I feel it is a good move as it is. You could even kind of make it likes thresh flaw in a way it cause kb away or towards diana depending on if they are in the edge of the move or more in the middle.
R: I was thinking Diana could throw a Full moon at her enemies. If it hits a enemy it stuns them and adds a moon onto them that after a while it will explode and stun anyone around that target./ Or you could just make it do a aoe moon explosion after it hits a target and aoe stuns anyone around them like sejuani ult. But I wanted it to be more unique.
Here is my idea of a different type of rework for Diana. I feel this would give her a lot more identity and allow her to actually be balanced. Plus it would also allow fighting vs her sister leona. Which I think these 2 should be doing in the first place. I don't really see why Diana wasn't a support to begin with. Plus her design as it is has only been nerfed none stop cause the toxic R that she posses.
