IMO it sounds like Hawk Eye Shot would be fine if it was not linked to any other JAs. As I think Double shot + Unlimited shot were only linked for easier programing. lol.

As for defensive-reflex, I think having it shed a % of the users enmity would solve the main issue of moving the mob around as long as it was a 20-50% enmity lost. However, after thinking about it just having it shed hate and not move the user would be much easier to add for the design team. (Hope they actually read this stuff as it seems like every RNG is just asking for 1-2 JAs that have timers and work like high jump and super jump. >.>)

IMO I think we should keep building on these defensive capabilities because they can really change how people look at a job. Some really great examples are when SE added JAs like Seigan, Retaliation, and perfect counter. Sure they don't make them invincible but they do make them more desirable.
