Sasuke never spammed techniques in his entire life. it's not his style.

Transplanted eyes cost more chakra, which is why Obito barely used the Paths. If Kakashi vs Obito or vs Sasuke is any indication, transplanted eyes cost dozens of times as much chakra. But Sasuke used nine Chibaku Tensei simultaneously, so he definitely can spam them. Like i said, he simply doesn't use jutsu spam as a tactic, he uses what he need to use in the amount he needs it.
