Please help a noon out

OK I have been rocking a 5/65 NF for a while and I must say I have been enjoying him a lot,contents are a bit easier,I think I fully get his kit and his uses but one thing that is really ticking me off is his Sp1 disorient,I have tried using it in different scenarios but it does nothing, please kindly help a noob out,what uses does his disorient have?

Disorients the Opponent, reducing their Block Proficiency by 50% and Defensive Ability Accuracy by 70% for 8 seconds.
So basically should mean less chances of their defensive abilities, e.g. magik less likely to go into limbo etc etc
