Can't join in-progress Arena matches?

[Mail]

I hosted an arena lobby yesterday and noticed that players could not join matches that were in-progress, they were put in the lobby and had to wait for the match to end. This seems like a major flaw, as most people aren't patient enough to wait for a match to end. Is there a way to allow players to join matches in progress or will there be an update that will allow them to?

I plan to update this yes.

Unfortunately last time I activated live-joining, it was highly unstable.
So please be patient as I try to iron out that feature before bringing it on.
