My group can't figure out the value of the Disorient Talent. For two advantage it lets you put a setback die on your target for one turn (per rank, but I'll get back to that). But that's basically what anyone can do with the basic list of things you can spend advantage on in combat (give target a setback for their next action). Sure the Talent lasts a round instead, but how often does someon take more than one action in a round? Almost never so far in our group (mostly people duck for cover, a manuever, and attack, which takes the setback).
Now Disorient being ranked helps, but the ability only appears twice in two different talent trees of two different careers, so unless your REALLY going for a build that uses Disorient a lot, it's pretty much just wasted XP (as far as my group can tell).
Can anyone enlighten me? Thanks.
