One of my offtanks in a DF of midas 2 (A6/M2) went this route and it wasn't a mistake because he had a proto midian ring plus rest 210 slaying, i dono if they knew there was a tankswap in M2 or not but the second he took the boss from me he dropped to the ground, i guess that 1% dps did him wonders. moral of the story, don't think for a second that STR is as valuable as VIT with it's same AP ratio, it's not, always the the parry and suck it up no content is worth wiping because someone decides they want to stick to the old ways.
