Personally I love Det right now. I don't know Sch well, and was under the impression Crit benefited them a great deal more.

Direct Hit adds more calculation since you can also Crit Direct Hit, and DoTs can also DH and CDH. The crit/dhit interaction gets messy, but will likely be sorted out soon.

Add in SpS influencing HoT and Dot amplitudes, and it can get complicated.
