Ranged LB not working on slopes

[Kapiz]

But can u really call it "exploit". So is using tempered will etc also a exploit cause I can dodge divebombs with skills like this too?

How is using a slope can be related to using an in-game ability that is designed for such attacks?
Before you reply with "slope is designed to avoid such attacks as well", no they aren't designed for such attacks for example: Chimera's trial where you it up and tank it above a rock and dragon's voice won't hit ranged at all, how is this not an exploit?
