Hmm, the stat weights between Det and SS are sooooo slight that you're not going to see a huge change in your damage if you choose to prioritize one over the other. But! If you do want to pick the *best* gear for the setup with the most damage potential... SS is technically the way to go... Hence, the term BiS. I'm not particularly happy about SS being weighted higher now, as I am not that fond of SS as a whole... and it's not just because I like to see bigger numbers with my direct hits. :P SS can lead you to go OOM faster if you are not careful (due to the direct consequence of casting spells faster than ever). But, as long as you aren't excessively spamming Ruin 2 or having to raise a LOT of people, you should be okay. Personally, I don't have mana issues unless I have to raise people and the fight goes on way longer than it should... The other important thing to remember is that you'll only really have to worry about mana in fights that have no long breaks, like AS9 and, to some extent, AS10. In AS11, for example, there are so many long breaks that it's really not a bother, even with the occasional raise. I've yet to finish AS12 so I'm not sure what my mana will look like by the end. I've always enjoyed Crit/Det (call me old fashioned...) so I was excited to see all the Crit/Det raid gear this tier... but of course, now SS is weighted higher than Det. SE is trolling us. :P
