I would make it neutral ground for at least the last 8 teams. Not sure about 16 last.
the benefit is that smaller teams with HCA might stay in a little longer, the downside is that the better team might get screwed, BUT I think that if the HCA delivered the loss, the diffrence between the teams wsn't THAT great to start with...
Now the benefit of neutral ground is that managers with a decent arena who do not participate in B3 might actually have a game at their arena, which might make B3 more exiting to more teams this way.
So my call: neutral for at least the final 8, and maybe the final 16. As long as 32 or more teams are in there, keep HCA.
They are not your friends; they dispise you. I am the only one you can count on. Trust me.
