Tank BIS is crafted acc's, that's a problem.

I can't find such spreadsheet and if what I said in my previous post is anything to go by is not that simple as full 340 vs 320 is a mere 1.03% damage increase you change the +2str to +3 and I think 340 set would be BIS maybe you know how it works more than I do and seems straigh foward but I've never digged into theorycraft so I have no clue how it scales off so is not so easy to make a solid assumption by just looking at the amount of substats vs mainstats.

1% direct hit is .25% damage increase on average.

Each melded accessory gives about 1.9% direct hit chance. Full right side is about 9.5% DH or around 2.4% DPS increase.

The strength upgrade would be +10 over a previous strength around 2000, or about a .5% increase.
