I'm probably wrong, but, I had this thought.. Every piece of raid gear is going to have more secondary stats then what we are able to meld. Like, at most we can add is 24 stat points since no overmelds. Would it be better to take, 216 acc off the target acc and just calculate the highest dps set with full acc melds? I don't know, just a thought I had since typically we've always wanted to take the highest weighted pieces and kinda fill acc in where necessary.
It sounds too goofy to be a good idea but almost makes sense to me lol. It may just not be a viable progression idea tho, since raiding is like a box a chocolates..
