>or is the fab community just really sheep-like?
I don't know what you mean by this, are you saying people are told what to play purely because of public opinion? Hardly, if that was true you would see way more quirky heroes represented. It's not a sheep problem, it's actually a wolf problem. It's all wolves at the top.

Top competitors are not generally class specialists, they play precisely what the top decks are. As another anon pointed out >>96336540
A new set generally introduces one "good" deck into the environment, if not several at once, and this upsets the ecosystem of how classes live and die by the numbers. Certain classes predate on others; simply put. Why is Gravy Bones is so popular? It's Shadow Illusionist, which is something that has historically been game warping and forces everyone else to play a different game against them. What are boardstate builders weak to? Assassin, Ninja and maybe soon Warrior. So in order to beat the top deck, you see an arms race of which predator can topple the current super predator. That's why you see numbers of heroes getting forced, because once the numbers from tournaments get published everyone follows the scent of blood on the air and plays what wins the most.
