Why are Leona's damage numbers being hit so hard?

For real, I want to know why you are nerfing them so much.

**Q: ** To 30/55/80/105 from 40/70/100/130/160

That's a 10/15/20/30/50/55 damage nerf per level. Why can't it be like 35/55/95/120/140 or something instead?

W:

to 60/100/140/180/220 from 60/110/160/210/260

That's a 0/10/20/30/40 damage nerf. Instead I suggest 60/90/120/160/240 or something similar but not hitting a 40 damage nerf at full rank.

R:

to 100/175/250 from 150/250/350

That's a whopping 50/75/100 damage nerf. Why so much, Riot? Please, change it to like 100/200/300 or something.

I know you are pushing her to utilize more utility, and are giving her E root blade duration a buff, and the new Incandescence ability, but the way I see it, you didn't need to hit the numbers so hard. For these kinds of nerfs I would have expected you to heavily compensate her, like a 1. duration on her E and increasing her stun/slow root on her R or something.

Not only does this hurt her damage potential in game (say the ADC is behind for example, Leona was a pretty good champ at getting some damage off), but now she can't do that as much because of this. It also hurts her solo laning. Now I know it's not as popular, but jungling Leona is very fun. People usually max her W for clearing monster camps- and she can't do that as well because she is losing 10 damage per level on her W, and 5-25 damage per level on her Q. Top lane Leona, I've never done it but heard people like to max Q for her AA damage. It's harder to do that now.

Please, Riot, can we get an explanation for this? I know I'm going to get some hate for it, but I honestly liked building damage on Leona and now I can't do that because you are nerfing her numbers a bit too much.

EDIT: Honestly I don't know why I'm getting downvoted. Please upvote, I'm just trying to get some answers from Riot.
