Geodew,
I'm from Ask Mr. Robot. I wanted to point out a few things about how we calculate set bonuses and trinkets. If you ever think they are wrong, hit is up and we'll take a look, adjust as needed.
Set bonuses: we run a ton of different scenarios through SimC with and without each set bonus. Then we find the difference and attribute that difference to the set bonus. Let's say the difference is 4k healing. We give that a value in the most related stat, like intellect. Let's say it would take 304 intellect to do an extra 4k in healing, we assign the set bonus 304 int. Then, as you change the stat weights, the set bonus is chosen dynamically based off the weights you use. Now, often we need to re-run these if simC changes something about modeling them, etc etc. So it's good to hit us up if you think something is off.
Trinkets: we run a ton of simulations on trinkets as well. We then do a similar process as we do with set bonuses, by assigning the proc to the most relevant stat. Even though we do all of that, we do suggest people pick their favorite trinkets, because often they time up with different abilities. Or some people like on-use and some people hate them, you get the idea.
As for set bonuses, we want to add a toggle for people to force them on/off to override the stat weight system.
And, items will be live soon on our site. There's one word of caution: they will be live BEFORE stat weight updates. So if you want to play with gear, be sure to change the stat weights as necessary.
