Dampen strength is based on light armor pieces equipped. So if you use a set of heavy armor as a magicka user(many do in PvP or tanking in PvE), the other morphs or Harness Magcika is better. Heavy builds also have more issues with resource management.
Go Dampen if using 5+ light while playing a build without magicka issues. Nightblade siphoning build, for example.
Oh yeah sorry I forgot to mention what I was playing. I'm a sorc with resto off spec. Magicka isn't really an issue at the moment but I'm only level 40
