Tanking should not be thought of like a DPS class, in that you need a specific rotation that maximizes GCD's and CD's to output the most DPS. In every tanking class in game (provided spec'd correctly & yeah i dont want to get into a class debate over which tank is harder to tank on) blizzard has gone out of there way to make threat gen relatively simple over all.

This is because while Blizzard want tanks to always be pushing buttons (hence the need for threat), they know good tanking is to a greater extent thinking about popping and cycling CD's/reaction abilities efficiently, raid/situational awareness, and ability to position/reposition boss on call.
