Hi scottz0rz,
The topic of Just Reward being a problematic talent was raised originally due to your posts from the beta forums, so thanks alot for that. Different options for how to solve the issue (old Encore, restore cd on kill but still allow regular cooldown, amongst others) were brought up but the suggestion to tie it to critical hits was both thematically elegant for Bounty Hunter, and feasible to implement and test on a rather short notice.
Regarding functionality; the current version allows Blessed Shot boosted ability shots to reduce the cooldown of the ability by 15%.
Regards,
Kasper
