I love you, you are so right. That other thread is nothing but people bickering with no data to back it up.
Let's get this thread filled with a ton of actually screenshotted data so we can prove one way or another how our damage is.
Dangerous way of trying to prove something.
Target dummies don't take circumstances in content (e.g. but not limited to operations) into account such as but not limited to player skill, raid buffs, debuffs on boss, AoE, movement, target switching, (partial) downtime due to range, utility, RNG (e.g. crit). To be fair, it does factor in relevant circumstances a sim would generally not such as UI lag (tho one could argue this is player skill which SimC does take into account).
To quote Elitistjerks shadow priest 4.3 FAQ:
Q: I changed my spec, and on a training dummy my new spec gives me more DPS!
A: What you do on a training dummy is irrelevant, not only is your sample data far too small to rule out RNG, you're also missing lots of buffs/target debuffs that will change the way certain talents perform.
Perfectly valid here, so you should take the parses with a huge grain of salt.
Besides, if a screenshot proves to you what a text quote does not then the obvious flaw is your misplaced trust in a screenshot. Newsflash: screenshots can be manipulated.
I'm far more interested in raw logs tho they'd require a log parser which is a complex piece of software. Target dummies are far too unreliable to provide any meaningful numbers.
