The whole point of this is to give access to a limited, yet specific type of reward you need.
And unparalleled challenges.
And simultaneously provide extra content, with kewl story/bounty missions (which can change and alternate) that give acces to this Super-Tough reward boards nodes, that get even more difficult each time you repeat it (up to 3 times) daily.
To add even more challenge some of these reward nodes can have specific requirements... like "must use CUP" or "ugnaught must survive" etc... you get the idea.
This is the challenge all the mega-whales have been yearing for. And the access to targeted rewards f2p has been begging for.
