4 months ago I suggested Jayce nerfs that got down voted.

In that thread, I suggested Jayce passive nerf from 40 % to 30 or 25%. It got down voted.
Today on the PBE: http://www.surrenderat20.net/2017/01/124-pbe-update.html#more
Transform (Gun to Hammer) bonus AD ratio lowered to 25% from 40%
I was spot on what nerfs Jayce needed. Next time, think before you down vote. I see a lot of reasonable nerf suggestions on the boards that get down voted by people who don't know anything about balancing. There are some crazy suggestions that obviously should be down voted, but a lot of ideas are actually good ideas that should be upvoted. My thread from months back is a good example.
