Unfair, nope. It's their list, they can do whatever they want.
But I can as well disregard it completely, knowing they have excluded very important aspects of CS:GO entirely.
If they weren't lazy, the lists would have looked entirely different in the past. Or would you prefer I simply called them stupid and ignorant, which I don't think they are?
Lazy is nicer isn't it?
I imagine they have a list of about 25 players which they have to pick from. Sorting out 5 players is probably the hardest work of the entire process. This is also where they risk heavy criticism on par with picking who is at the top.
6-15 is where it doesn't matter that much, and they can fuck up a bit, because it isn't noticed as much in the end.
