Nice guide!

I just have a couple questions, first question: In 4 man content is it generally better to use an Expanded Balance on the whole party or use an Enhanced/Extended balance on a single DPS? What about just a Balance on a DPS versus Expanded Balance on the whole party?

Second question, this is more in terms of gear stats: I usually go for Crit over Det and I don't know if that should be the other way around. Am I prioritizing secondary stats wrong?
