Polls are useless, every one is aware the community wants it. EU wants it, NA wants it and now Oceanic wants it. ESL are changing their rules for the Aus ODCs and i have no doubt Jamstah etc will follow suit.
That is until Blizzard announce their own ruleset that may or may not have hero limiting regardless of the opinions of the pro players around the world.
Bring it for the ladder and ODCs by all means, it's not really a debate i haven't seen a single person with a solid reason other than "I WANT TO PLAY HOW BLIZZARD WANTED ME TO".
