What were Mr. and Mrs. Bumblebee doing on Valentine's Day?

Well, this has to be a first for me. Doing the daily mission for the T3 Tactician spark and EVERY single opponent bot was Bumblebee. I noticed a recent run where I faced a crazy number of Megatronuses, but a full compliment of Bumblebees is incredibly odd.

Is it just me? Are bot distributions random, or is someone playing a joke on us by putting BB on every single node?
