You're either not getting it, or deliberately obfuscating to protect your status quo. The actual numbers are irrelevant without a context to interpret them with.

When your latest and greatest Fellest Cleave is doing half the damage of the weakest dps doing a pirouette next to you, that relative difference is what you're going to base your interpretations of what 'strong' is. The devs want to sell tanking with these flashy appearing 'big damage' moves, but relegate you to afk punching-bag duty when you enter raid content. The balance has shifted way too far the other way.
