So, I got lucky and beat the boss node, but I did NOT receive the command point which is supposed to be the reward. It’s bad enough that the boss node is 99% unbeatable AT ROUND THREE(!!!) but then to get cheated out of the reward at the end just adds to the general suckiness of this event.
Par for the course for this game. 
A command point is not an automatic reward. There are 8 possible rewards when you beat the boss battle node. As far as I can tell, you can randomly receive any of those rewards. If you beat the node multiple times, you can earn additional rewards.
You did not get cheated, you received as reward that was listed. Look closer at the node to see the possible rewards.
