You guys shouldn't worry about bad players this much, seriously. FFXI had a small community, FFXIV will be the same. If someone is bad enough it will spread fast. Kick him from your party and blacklist him ... he either starts playing properly or simply quits the game since he can not get a party anymore. I do not see the problem.

I hardly played with bad players in FFXI. There were lots of them. I hardly played with bad players in WoW .. there were millions of them. It is me that decides who I play with so why should I care and worry about someone being a bad player? Get over it already.
