Parses climbing then falling

[proud forge]

This applies to pretty much all encounters. Not sure why but as I have gone up in gear I seem to be parsing significantly lower and I'd like help to point out why that might be and where I am going wrong.

There is no fight in particular as they all have the same trend. I am not sure exactly what to look for so any help would be much appreciated and I can link/show anything else that might help

So to your point t about parsing lower and lower with more gear… that’s simply because you’re not the only one getting more gear. People that simply play better and/or have a better raid group in general outpace you.
