Grapple Hook is already a mobility/escape ability that comes with tough restrictions: aiming your trajectory at an appropriate surface, the delay between activating the ability and actually getting movement, the trackable straight-forward line she moves in, the inability to shoot or use other abilities while grappling, and to top it off, it’s on a decently long cooldown. If Widow doesn’t land herself in a good position, she’s stuck grounded for 10 seconds, making her extremely vulnerable if she isn’t able to make an escape.
Breaking the grapple by damage does not seem right to me. Mobility abilities are meant to be fluid and hard to interrupt, and that’s a rule for fun. If any decent scratch damage could cut the grapple, it would feel inconsistent and very awkward to use, since not only are you being denied an ability by something as conventional as just damage, but now you’re going to be misplaced by your own ability. This would also mean that if Widow was being hounded by Winston, she just wouldn’t be able to escape at all, short of finding a window where Winston is reloading to grapple away. That doesn’t seem right at all considering Winston already has an immense advantage against Widow – people really want to deny this, but Winston shuts down Widow extremely easily and makes her very difficult to get value out of, so I’m very hesitant to give Widow a nerf that makes her even easier to die against Winston.
Widow does not need to be more vulnerable to dive. Her having an escape option is not a problem – virtually all DPS heroes have either some sort of “get out of jail free” card or otherwise have something else to compensate. Reaper and Mei can become completely invulnerable, Tracer can rewind time, Soldier has no cooldown on sprint and access to a self-heal. All these characters have responses to situations where they’re being caught out, and they have those responses because it’s engaging to have enemies that can try and make a comeback. It makes for interesting dynamics when characters aren’t so hard countered that they can’t possibly get away or hope to turn things around the moment it starts going bad for them.
And for Widowmaker, that ability to escape is not a guaranteed escape, and it’s also the same ability she wants to use to access the best sniping positions in a map, it’s the same ability she has to use to take aggressive and forward angles, it’s what she has to use if she wants to chase after enemies. So the fact that this ability also has to make reservations for an unsafe escape, to me, doesn’t seem incorrect at all. Grapple Hook is a great ability for Widow and how she’s meant to interact with the game, and while I can definitely see it as an easy place to nerf, making it inconsistent like this is not the right direction. Lower the cooldown, decrease its range, other tweaks could possibly work, but what people seemingly want is for Widow to be a free kill the moment D.va or Winston are even being played – they want Widow to be useless, and they think that’s fair because uhh headshots I guess, and they don’t realize how difficult the character already is to play, let alone how unbearable she’d be to play if her one mobility option was denied to her if she’s ever taking damage (aka the exact situation she’d want to be escaping from).
This is a fact about Widow’s design that the community is going to have to accept. Widow was meant to escape using Grapple Hook, it’s hard for me to imagine they’d nerf it like this and not at least also give her better power elsewhere in her kit, and do people really want that? Like I said, they don’t – they just want an easy-to-kill Widow that doesn’t challenge them to navigate maps properly or execute dive tactics correctly.
