Wobbles is a great solo commentator (and an amazing so-Po as well), while he doesn't seem to compliment co-commentators. Prog, D1, Dogy and Wife are all great choices for co-commentators. Dogy just needs to ease up on being so assertive sometimes. I've noticed a few times at the past few Apexs he usually gets too wrapped up in a matchup he remembers seeing a lot back when he played, especially when Doc is in the mix.
I understand your love for Doc, Dogy. I'm a fellow Doc main as well. We are a proud people. However, you never hear Prog or D1 talk about their mains in every time they see them on stream. You just gotta ease up on that dude, then you're arguably one of the best Melee commentators around.
I'd also be okay with Waffles doing some commentary for teams. Teams is usually pretty boring and Waffles livens it up. He's a little too much for my taste when it comes to singles matches though. I like a healthy balance of sensory input
EDIT
Forgot about Mango and Lovage! But along with Wobbles possibly, I would think that they'd rather compete. But if they can do both, then go for it.
