I know a lot of people are going to be against a buff for Breach, and I know he can be super annoying, especially at lower levels of play, but hear me out. He is arguably the weakest Initiator at the moment, and he is also the only Initiator without any info gathering ability. Kay/o has his knife, Skye has flashes AND her dog, and well Sova is Sova. At the upper levels of play (which keep in mind is how the game should be and is balanced for), info is everything. Hence why Breach is very rarely picked, even with his kit changes (The flash changes to Skye make her better at flashing too which is a whole other discussion).

With that said, here is my suggestion. Give Breach a voiceline when he stuns someone with his Fault Line. Simple as that. Just like how Skye flashes work, but his Fault Line. Lets him gather info with it and brings him in line with the other Initiators. Also, all other Initators have info gathering abilities that refresh after a timer mid-round (Sova arrow, Kay/o knife, Skye flash), so it makes sense for his Fault Line to be the one which does it.
