Why did Varka take all the calvary and not the cavalry captain?
Because he didn't want to invoke Diluc's wrath.
Yes, he was away on his Fatui hunting spree, but if he came back to find out the man who let his father died took his brother on a years long expedition? The entire city of Mondstadt would've been burned to the ground.
No, of course he doesn't say he blames Varka for that day, but he is the Grand Master of the knights, who else would he blame?
Oh, and Kaeya was always just a place holder. He needed to be in Mondstadt to hand over the position to its rightful owner
