the voice chat bug happens to me all time when i play through Bnet client, so hooked my account into steam and not once have i had the bug again and voice is always working. It's definitely a Bnet client side issue.
Honestly, just give rein like a slightly better movement speed so he doesn't feel like he absolutely needs a Lucio to do anything. Like not as slow while shielding would already do wonders.
I swear I never see a good Kiri ult in your videos since I started watching lol. All of them are at weird angles, when the fight's over already, or just... in weird places.
I love it when aimlords like cyx get humbled by spray and pray heroes. Not letting these cs go/valorant type players into our game is how you make it fun for the majority of playerbase instead of sweatlords like him.
