Lux Shield

I'm just curious; how much testing was done with the new lux shield mechanic before it was released to live? I'm not crying cause nerf or anything, but it feels really clunky to play with. The range seems longer, but it feels like it takes a year for it to return. I only play Lux as a support, so I used to use it pretty often, but I think I'm better off saving the mana at this point. Again, this isn't a QQ thread, I'm just asking a question [slayer-jinx-catface]
