So, I decided recently to go for the DSC raid seal. I have nearly all of the required triumphs, but am still missing the Not A Scratch triumph, which requires bringing all six pikes to the final bubble. We did that TWICE yesterday, with a full team of six, even br riding each pike through all of the bubbles, but the Triumph did not pop for me. The rest of my raid group already had the Triumph, so I couldn't check anything there. Does anyone know if there's another hidden requirement in play here?
