I've been watching Tevin for a few years, now, and the whole talking over Phil thing is something I've only really noticed this past month or two. But honestly, after restreaming the pig for years, I can't blame him.
I like Tevin himself, but yeah, the TTS is unbearable. The first Mario 64/Cat reveal stream is probably the worst I have ever fucking seen. Like, 10 messages in a row when Phil was on the first stage alone. Sometimes Tevin is merciful and stops the emoji spam messages early, but sometimes he just let's them play. And fuck his chat with the constant CAWs.
At this point, I only tune in if he's doing a special video, like a Goin' Back in Time.
