FIFA does not, as they understand how make a competitive product (and take bribes).
The Faroe islands (and Andorra) compete in the FIFA World Cup under the same conditions as France or Brazil (well, in the qualifying rounds at least).
And if 10+ players is too much FIFA also hosts Beach Football with 5 players on each side (and with other changes as well).
And FIFA doesn't prevent anyone else from playing either of these games -
at their own level
(you still didn't understand what it means, what is their level = their stage of progress (wich should ≈ content) in expansion, I see that you think that you can hide behind E-sports alike system while you continue misunderstand even it, and which even in originally conceived state is still not applicable to this game; good luck on goof off for you then, I see no reason to validate myself at the expense of miserable people).
And similarly in other games - you are free to run 100m or marathons
outside of the Olympics; and as long as the tournament has a
certain level you are competing against the world records.
I see your vision, and it's a hollow wasteland.
(no you don't )
(And I don't understand the nod to Ulduar - that had at least 4 difficulty levels and wasn't in Vanilla.)
