So which is the problem? Brigitte being too scary or the two of them not being scary at all? Roadhog and Doomfist are a bit of a pseudo counter to Dive, but due to how easy it is to dodge their oncoming CC and the long CD of the hook, they’re just pushovers and free targets for Dive
Brigitte is the only character who can effectively fend for herself (and her teammate with armor) against Dive, whilst being a big enough threat that Dive Heroes would sometimes avoid her.
With Roadhog, you throw your hook and miss/ gets dodged, that’s it you’re free charge for 8 seconds and you have to run for cover. Not the type of presence I was expecting from a Hero like him
