so we get a 1760 seeker points for having all rank 30 lego items but having all rank 20 greens there is nothing. This could be an easy cr boost to help many get closer to the req for i5, for me just having 110 per green would let me break the needed cr wall.
They didn’t give us an extra 1760 cr for 30 lego. They just classified and named what was already there as seeker points.(220 x 8 = 1760) Even if they include 192 x 8 = 1536 cr for 20 green in seeker points, the cr doesn’t change.
None of the three seeker points, ancestor tableau, lego upgrade, helliquary are bonus points. They are what we already had.
And if you take a look at the Upgrades of the green Set Items, there is still the part +CR instead of +Seeker Rating.
So you already have max additional Combat Rating if all are Level 20.
There is not “nothing” since the change. 
Oh well haha late night thoughts.
