There is also a large skill component in executing mechanics (especially those involving lots of movement/concentration) while losing as little DPS/HPS as possible.

Tank/spank fights are a prime example of ~zero skill fights though, and why FFXI's skill ceiling was laughably, horribly low (as well as lacking any complexity/speed).
