Now, the team is making some more changes. According to a blog post by designer Geoff Goodman on the Overwatch forums, the team is re-balancing the Hook again.
Added some more line of sight checks towards the left/right of a potential hook target. This means it should be easier to hook someone who is sticking halfway out of a doorway, or behind a thin pole, etc. These checks are also used for the persistent line of sight check, so if a hook target moves behind a slim object like a stump or a lightpole, they won’t be released anymore.
Hooked targets are now slowed heavily while they are stunned, even if they are in the air. This means if someone is strafe jumping away from you and you land a hook, they are a lot less likely to slide out of line on sight, breaking the hook.
Fixed a bug that could allow you to hook someone and pull them behind you if you spun around before the hook landed.
Changes to Ana and Sombra have also been detailed.
Apparently Ana’s Biotic Grande duration has been reduced from five to four seconds whilst Sombra’s Hack cool down has been reduced from 12 to eight seconds.
