I present the player breakdown of the largest single 40k competitive event, the 256 player Warhammer 40,000 Championship. Take a long look at player-codex breakdown and weep my friends - weep.
Grey Knights at 22% equaled the total of the bottom 9 codices!
Grey Knights, Space Wolves, and IG equaled 50% of the field.
Not one Tyranid player was on the floor - not one.
I don't know about you, but I consider, Tyranids, Eldar, Orks, and Chaos Space Marines to be bedrock, foundational parts of the Warhammer 40,000 universe, yet here we are at the twilight of 5th Edition and between all four, they barely muster 11%.
I'm expecting BIG THINGS out of 6th edition to help this out.
The floor is your's folks.
