In all honesty, do you think that GF actually does some beta testing for competitive battling? All the nerfs they've done in SM utterly reeck of half assed attemps at correcting many stupid oversights that became glaring problems as soon as the games were out (for example: look how they nerfed parental bond, and fucked with talonflame's life).

And remember that masuda officially stated that they didn't expect people to run special aegislash.
