Why Remove Custom Stat Weights?

Hey,
The stat weights I was utilizing were from SimC based on my current gear. My BIS gear list based off those did not agree with AMR. It seems from the current AMR system (I could be wrong here) that all secondary stats (Crit, Haste, Etc…) are equal to each other and Primary Stats are always preferred but in my destro research Int is actually WORSE for me than secondary stats (This may change as I get more gear because secondary stats have a steeper diminishing return vs primary. I utilized the stat customization and the piece I am concerned with is I cant make Int less valuable. I just don understand why AMR would limit the type if gear I could go after based off my research and sims.

Why would we take away a feature especially when there can be different play styles? Destro lock this is less impacting but for example when I played a H Pally last expansion there was a divide among top H Pallies on how to gear (One route was more Crit based and the other was more Vers based) with the current option it seems to take away on exact weights I could utilize based off my research/preference and forced to do things the AMR method but I never have agreed with AMR stat weights and it seems that is still true but the other tools on where to find upgrades or what bosses to roll on was helpful based off my current weights. Perhaps I prefer to see the “weights” the current AMR sims and see if my findings match and adjust as needed but that seems impossible in the current methodology.

Edit: I understand weights will not include things like azerite or benthic but I think as a paying member for a product I should have the ability to adjust weights for primary and secondary stats based off of my Sims.
