I'm still really, really new (comparatively -- had an account since August but very little time to really play) but I'm finding that this game lends itself well to niceness.

So far, it's mostly FATEs where this happens, but I love being a healer, showing up and getting peoples' back. I love running in as a tank and grabbing one of those world-boss type mobs off a heal/DPS player who's obviously struggling. If I do nothing in this game but make things slightly better for people I come across, it'll be perfect.

Other than that, the fact that you don't 'claim' mobs you attack helps reinforce the idea that co-op can happen anytime, anywhere. If I had only one suggestion to improve things, it's to make it so that buffs are castable on non-party members (because I'd be throwing that around like crazy)

My advice to everyone is this: When something good happens, no matter how minor, and other people were involved, always /happy.

Seriously, it is the greatest emote.
