When were they not kings?
At the start of Legion, warlocks were the worst dps class though EN. Our lock from WoD quit because of the state of the class.
The funny thing is sims are getting further and further off as gear gets more inflated with stats. In EN people could reliably count on sims to give them a decent estimate. Now?
My sims are literally 300k off. Anyone who still uses sims as a guide for their class can be safely ignored. They have no fucking clue.
As far as I remember, the Simcraft people have always said that using sims to get DPS numbers to compare classes/specs is not the proper use of the tool. It is for helping with gear choices, full stop. I am sure you could go through all the options and maybe set up one of the simpler boss mechanic fights, but no one does that shit when you see these simmed dps figures released.
In regards to the rogue nerfs, if you use some napkin math you dont need sims to tell you how much it will hurt. For the shoulders, take a gander at logs, see how many times you vanished, and figure out how much you will lose on that last ability that wont be 100% crit. For the boots, it shouldn't be that difficult to figure out the average amount of combo points you lose over the course of the fight. Not that I am going to do this, cause I hate the lego system, so fuck em.
RNG on trinkets is somewhat normalized over 6-8 minute fights I thought?
Maybe?
One of the problems is building every trinket into every meta rotation, every time Bliz decides to change things. Some classes have better support on sims, than others. Rogues always one of the top supported classes, but not sure where other classes/specs stand.
Even if the sim for your spec is 100% accurate, trinkets are probably the best example of the weaknesses of the sim programs. The difference between perfect play and real world play is the most pronounced when you dont have plain stats to feed into the calculator.
As an example, take the Specter of Betrayal (melee dps trinket from KJ), sims will have it lined up perfect, so it will always sim high, but if you miss placement, or the boss moves for what ever reason, the trinket can be less effective than a stat stick.
