Thank you for mentioning that list of projectile abilities. I was actually looking for that the other day and didn't think to look on the Arachne page. Wanting to also test those with the Mutalist Quanta bubble.

I really think Limbo was a bad idea in general. He's a very clunky frame that causes frustration for the rest of the squad, with the amount depending on how much the Limbo player is willing to actively try to mitigate it. When his abilities are able to consistently function they have also historically completely trivialised game modes. There's not even a good way to fix these issues without turning him into a different frame entirely.
