You perfectly explained why he is labelled as “Advanced”.
Also, if you think Benedict need a buff, while knowing some can play him really well, you are going to turn him into a killing machine for whoever already can kill others without much problem.
Also, that mean the character is fine, you just need to know how to play him. Which is why i made a Guide and a Build for him in this very own section.
If you mean the “Get X kills while being in midair”, it’s actually pretty easy? Don’t know why you have so much trouble with it.
Aim for their faces? It’s a single rocket kill, and they don’t move much.
