Stop splashing regular Nerfs into off meta picks!

I don't understand, this is mainly regarding the Nerf to Lucian coming in the next patch, they are reducing the damage by 10 and upping the mana cost by 20 on his W "ardent blaze" his AP ability! If you want to nerf Lucian that's fine, he is a dominant pick right now, but why nerf his off meta play style? it's not like AP Lucian is sweeping the meta off it's feet right now. I very much enjoy playing AP Lucian and I actually play it competitively to the point where I've created build guides to instruct other players how to make it work successfully. But riot consistently has done this, when tristana was strong, they lowered her AP ratio's, they took the AP ratio off of caitlyn's traps for seemingly no reason, Nami and Sona have some of the lowest base AD's in the game making it damn near impossible to Last hit in solo lanes at early levels. AD Zoe could have been a thing, but riot nerfed more sparkles instead of literally anything else, and don't even get me started on Rakan (who's now impossible to solo lane as) I don't get it, for a company who constantly says they want to see they meta change, grow and adapt, they are making it very very hard with every new patch to do so. I'm not saying don't nerf overpowered or dominant picks, but I am getting tired of the targeted nerfs being splashed into the off meta play. You can nerf the strong aspect of a champion without nerfing the whole thing and ruining off meta builds.
