@riot Lux nerfs are in the right direction but...
I think rather just nerf the value of her shield, make it t where it doesn't refresh on return. It can either shield on way out or way back but the refresh is honestly what makes her so annoying when u do "catch her". I main Lux and I play against Luxs when I am jungler. I know how to punish Lux. You gank her when she over extends. But as I do when I am caught out I can insta cast the shield now and soak up some damage then on return soak up more. Combine it with barrier and you have a lot of "effective" health.
Maybe I'm wrong and just nerfing the ratio and base all help, but I think getiting rid of the refresh is just better overall.
