And this problem will always exist so long as the community continues to have this mentality about numbers and blindly follow what we're doing without any reason to. You can make all the balance changes you want, no game will ever be "perfectly balanced" and we will always find an optimal comp. So as long as this mentality continues, the community will continue to blindly "exclude" any class that we do (simply because they see us doing it and they'll hear us say that one comp is stronger than another) even though there's literally no reason for them to be doing so.
Instead of trying to make balance changes based on this false perception, we should be trying to break that mentality so people stop circle jerking and we stop getting threads like this making completely false claims and then people misusing parse numbers in an attempt to justify it. And for the people who are committed to raiding, perhaps they should take a little bit of time to actually understand how strong or weak a class is when played optimally and why the "meta comp" most likely won't matter.
