Can you explain to me why is it just about guaranteed to attract those discontented with the current system? Really curious since I disagree. There's more than 800 people that voted, I would say it's a good sample from my experience with election polls which are usually done with 500-1000 people and you would be surprised how accurate they can be.
Having 65% wanting the change in the system where 90% are raiding 10 man says a lot. Having 43% wanting higher ilvl for 25 man says even more.
