is five boxing pointless atm?

[Fat Tire]

Five boxing is more viable today than it was pre expansion if for no other reason than challenge modes.

3 boxing loses a lot of advantages that come with multiboxing while still suffering from the same disadvantages.

I couldn't disagree more. I would be curious on what advantages I lose with only boxing 3 compared to 4 or 5. Given that the other +1 or +2 are not bots.

Top challenge mode rewards are only cosmetic in nature.
