Tentative DRG BiS is currently one of the following two builds:
Floor tank at mach speed!
Crit Machine!
In the latter case, you will meet thresholds with those pentamelded accessories which makes up the loss in STR. That being said, the difference isn't too substantial if you want to aim for full i370. Of course, this is all based on early theorycrafting, so it may change. If you opt to try the Skill Speed build, I highly recommend testing it out on a dummy first. You will not be able to double weave whatsoever at that level, so there will be an adjustment period. I put together a relatively easy hodgepodge of gear just to hit 2,400 and see how it felt.
