Knight Tactics didn't exist when /Zero was created. Its sole purpose is because Diarmuid only otherwise has two non-MR skills, so when he was released in Grand Order a skill needed to be created to fill the gap. Since that skill is simply one big reference to fighting against Saber, it doesn't actually add any ability that he didn't already possess--said skill being EotM. Knight Tactics is literally just a way of describing how EMIYA survives fighting Cu ffs, which is EotM.

[quote]Assassins already get independent action as an off-screen skill at B- rank.

I don't think I'm missing any point, here, unless independent action now abbreviates to a completely different skill.
