Because they constantly act stubborn then desperate in that order repeatedly ? They constantly refuse to change things because of their "vision" then constantly scramble and add patched together half baked system when the community warning them that their vision is once again ill conceived and so conceptually flawed it can't be fixed only made non relevant ?
It's to the point when blizzard brings up their "vision" the community immediately brings up their success rate. If they want praise they need to actually learn lessons and take feedback not haughty dismiss warnings then scramble in a mad dash to put in anything to offset their fuck up.
I am not pretending the top Player base are some saints of game design made manifest. Odds are they would want a very conservative approach to design and would rarely if ever want to see things made outside of the three pillars. I wouldnt turn to them for designing content but rather use them to utterly rip to shreds content being developed and have the faults drawn out in agonizing detail. Blizzard doesn't need idea men right now. They need people to tell them no.
