According to Geoff Goodman, you can expect changes coming as soon as this week!
Blizzard was presumably getting fed up with the daily complaints about Roadhog. “Roadhog hooked me through the wall” “Roadhog hooked me through the payload” “Roadhog hooked me at my kid’s birthday” It’s not so much that he is OP. But some might argue his hook is.
The first change is Roadhog’s chain will no longer move in only straight lines. Goodman does mention a limit to how far to the side you can grab someone.
The 2nd big change is Roadhog can no longer hook people he cant see. So no more sticking your hand out of windows and yanking people!
And lastly, there is a new “persistent” line of sight check. This means is, if you get hooked and fall off a cliff or dash. The chain will break instead of pulling you back up.
It will be an interesting day for Roadhog mains when these changes hit!
