One thing I notice FF14 has that WoW simply doesn't have is Practice groups in the Party Finder. And overall they're quite nice, I've got all of my initial SB EX Primal clears through Practise groups. You get your mix of bad groups and good ones but overall it's a reasonable experience.

In WoW as soon as week 1 has passed, all the party finder groups are 10-20ilv higher than the loot that drops from that instance, must have multiple clears, will check your score on third party websites. And if you dare wipe the abuse and insults start raining down. Maybe others have different experiences, but I've preferred pugs in FF14.
