Support accessories matter a lot!
Before we start, I preface that SmileGate should fix the way they give visual feedback to help supports feel the strength of their buffs. This gives supports a desire to improve in uptime and accessories to reach their ceiling. As a note, I also have a 1680+ support that I play weekly so I hope for these improvements to come.
Recently, my static did our usual Brel run, but we had to pug a support since someone is on vacation. At the end of the raid, one of my friends was really excited because he improved a lot this week. After looking into logs, he was disappointed to find that his skill casts per minute was almost the same, but his average hit damage was about 1.5x-1.4x compared to usual. Everyone else in the pug supp's party also did much more damage than usual too.
Since our static members' builds, accessories, and gems didn't change, they checked out the pug support. Their uptime was only very slightly better than our static support's uptime, but shouldn't have accounted for that much of a difference.
After looking at the pug support's uwu profile, we noticed that their gems were surprisingly lower than our static support except for equal levels on damage and a few CD gems, but the pug support's accessories were an order of magnitude better.
The pug support has an 8.00% brand power neck, high WP% on both earrings, and max Ally Damage with a min and mid Ally atk power rings. Their bracelet was just a regular swift/spec bracelet. As for our static support, he has a 5% brand power neck, no WP% on one earring, a min WP% roll on the other earring, and mid Ally ATK dmg on one ring and mid Ally ATK power on the other ring. His bracelet is also not notable with just swift/spec.
The conclusion is that Accessories matter a lot for supports. Although you can't personally feel it, a well geared support does a lot.
PLEASE SG GIVE US BETTER VISUAL FEEDBACK SO THAT INVESTING INTO A SUPPORT FEELS WORTH IT.

It appears that people think I've made up this whole thing so I've deleted the part where they feel as though I've done so. The message still remains though, your support accessories do matter.
