Sure, it is simply the most obvious one, but it is by no means the only thing that is OP on both sides.
In my opinion, RB should be for shure nerfed in some form, but certainly not without touching the rest of the whole balancing issue.
With threads like this one, I’m a little afraid that the developers will only take out one thing and that the game then will continue to move towards total unbalanced.
I think most of those who want an RB nerf here see it the same or at least similarly, because it is often referred to the overall balance.
But, after what is currently planned (see Developer Proposed Game Mechanic Updates - #14 by LouisdeFuines no balancing overhaul), I’m more in favor of not touching RB for now.
