You are right, he is so wrong. My new sniper and Murmer have the agility perk, but with. MIDA I run faster and move quicker. I run past everyone when running. I am not a great player and haven't done the new raid yet but tried to do the first part solo without the exploding light lol. I actually was able to run past the thrall to the bridge making part where I was finally wiped out. Makes this old fart feel young and limber. No better primary or me, except to use Vision of Confluence in VOG against oracles.
