Before the rework, Rengar used to have 3 base AD per level.
Right now, it's 1.5 AD per level, which is the same as Janna.
When you know that xin zhao received a buff to his base AD, now to 5 AD per level, it's kinda frustrating.
The nerf that was made to Rengar's base AD killed the possibility of build any sheen item, which really sucks tbh.
I know we're getting a +8 base AD buff on the PBE, but it's just compensation for the old runes, and personally, i'd rather have
more AD per level than just +8 base AD through the whole game.
