The bias in the gameplay boards

As someone who one tricks a champion that did not really benefit from the lethality changes here are my thoughts:

So pre-lethality buffs:

"ADCS are literally useless" "AD Assassins can't do shit because they don't deal enough damage"

So now Riot listens and buffs Lethality. So now AD Assassins such as and actually feel pretty good to play and ADCs have made a comeback for the most part.

Now you guys are complaining that it's too much? That the champions that build lethality deal too much damage? My question is why aren't there any complaints about the mages who have been dealing crazy damage for awhile now? The other day I was watching Imaqtpie stream and he was playing support and he literally 100-0'd the enemy adc by himself with nothing but in his inventory. But this isn't being complained about because it's a mage right? What about the "oh that champion hit me with a skillshot, I guess I'll die or lose 70% of my hp" champions?

I just feel like the boards have a huge mage bias. Especially when I see threads asking for nerfs being downvoted heavily even though they are pretty well thought out. I also thought it was pretty funny to see many complaints about in particular. An item built to protect AD champions against these mages.
