The cheesecake runaway

[BigJ]

I don't think any arbitrary limits need to be placed. I can't think of any other year (since 2007) that "cheesecake" would affect the outcome of matches and makeup of alliances to such an extreme.

The closest I can think of is the minibot race in 2011, but even then a 3rd alliance partner could run at least some interference on the opposing alliance (depending on how good their human players were).

In 2015 a lot of alliances just had no need for a 3rd robot in their strategy aside from "[Burgle cans/tether to ramps/scoot the auto totes] and then sit out of the way next to the wall", and this was caused by the non-interactive game design.
