I think its pretty normal if that person isnt used to a controller, all of my friends and I use a controller on rocket league and the community fully supports it, not sure why kb&m is still making the community rage(I am aware that in both of the cases I mentioned there is an advantage but I feel like its just preference of what your used to, unless you literally buy a keyboard and mouse with an adapter and learn it just to reck people on console, now thats pretty dirt cheap)
