Viable to multibox action combat games? Specifically upcoming game Dauntless.

While I'm not the best authority on the matter, I would have to say that the answer is most likely "No".

1-1 broadcasting is at it's best inaccurate, which is why we rely on mechanics such as Follow to move around in most RPGs. Mirai demonstrates the issue here. You'll probably end up with characters out of sync very fast, with no way of 100% syncing them again outside of any teleport/instace portal mechanics the game might have available.

The controller adds another hick up to this as well. While I'm fairly confident the buttons themselves could be made to work, the thumbsticks are another thing. I'm not aware of any multiboxing software supporting the way they work for turning and movement. I.E. having multiple "speeds" from the same input. It's similar to mouse movements, sure, but I'm not sure functionality exists to tie the 2 together.
