You can't know the stat weights until people have done some testing. It takes hours and hours of experimenting on dummies and number crunching. Even if det is getting boosted, it's still linear, unlike crit (quadratic) or sks (inverse linear), so there may still be a viable breaking point where crit/sks surpass det. Just focus on levelling and getting the highest ilv gear you can get while the theorycrafters figure out the new formula and weights. Right now no one knows what's better or worse.
