I read something and talked to a friend to confirm. I haven't been able to find anything official about zeni to confirm or deny.

Is it true there are no decreased xp for grouping with others? and...

Is it true you get a bonus percent xp for grouping with others?

I am fine with the first because you shouldn't be punished if you want to group with others to do things in an mmo. But giving a bonus to groupers feels like it's punishing the players who can't maintain group play to the extent some of the hardercore players can. I mean I love my guildees and we will all be playing at launch. But I don't want to HAVE to group with them when doing single player quest content. As the rate I do that content and side things I do while playing may be detrimental to grind group play. (plus my girlfriend likes to pull ten times the mobs you need to to do anything)

I think the benefits of group play is that you have more options via class toolset then a single player experience and that's it.

Most games give you a bonus to exp if your group is all within a small range of each other levelwise, and a decrease if its lopsided.

With that said I don't remember hearing one way or the other yet in this game.

I think the extra experience comes from the fact that you will increase your finesse faster in a group than you would solo. The more finesse you build up in a fight the more experience you are rewarded, along with more loot too. But don' quote me on that, because I might be wrong.

I think they said groups get a slight bonus. Bug I'm not for sure.
