Again, it's a matter of experience. If you haven't experienced the problem, then of course you can be adamant about saying it doesn't exist.
It does.
I've been playing a very long time across the wide assortment of D&Ds/Pathfinder and the problem exists. It exists in most games that employ a system where someone gets powers beyond what the others can claim.
Are there ways to deal with it and be happy? Sure. But I'd be lying if I said that it isn't there, and that it could be addressed, that there are things that can be done to smooth out the system a bit.
If you haven't experienced something, don't discount others experiences.
