Hey, so I would love to be a shoutcaster. I have done it on my own on public servers, a couple mid level scrims and demo reviews, and I've been at it for a few years off of Twitch and now on Twitch. It may not be amazing but there are some examples of my work at twitch.tv/scootzii. I thoroughly enjoy casting and even if I need to be a reserve, that'd be fine.
I'll send this same info to your Discord account you have above as well!
