Group experience changes will be coming soon to EverQuest II. These changes will affect group multipliers and encounter bonuses while mentoring. Terrogaunt posted on the official forums today clarifying what we can expect from this. Continue after the jump for more details.

Group EXP Mult changes
Our multiplication goes down based on how many members are in a group. This is how it currently works and will continue to work. 

When you're able to get yourself onto the hatelist (there are a plethora of ways to achieve this), you will earn yourself the amount of exp that you would have recieved in a group of Yourself + however many mercs are in the group.

This means: Group of 6 ( 4 players, 2 mercs ). The exp for participation will be that of a 3-person group instead of a 6.

If you DON'T get onto the hatelist, not a single thing will change and you will recieve the same awesome experience that you've known for the entire time before this change.

Encounter Bonus changes
Encounter bonus is a seperate bit of experience that you get after killing all of the members of a linked encounter. This exp is not influenced by the amount of party members in your group. 

Before, we were giving this to every player in the group regardless of participation. This is the only change that might get you less experience. 

Encounter bonus will only be rewarded to players who are:
-On the hate list
-Have mobs conning higher than green
-Are not mentored

I've seen the mistake made before, so I'd like to clarify. Encounter bonus is NOT the bonuses multiplied to your raw exp amount. Having veteran bonus, vitality bonus, exp potion bonus, etc will still go into effect.

Q: When you say "Are not mentored", is that referring to players who are getting mentored or the players doing the mentoring?
A: This refers to the player who's actual level doesn't match his current level. The player who used /mentor and /unmentor.

In addition to above, the veteran experience bonus for having a max level character will be moved up to level 95 when the expansion launches. Any questions or feedback on the group and encounter changes can be added to this thread on the EQII forums!
