Diminished XP from "Raid" grinding
I'm not exactly sure what the formula is, but I was under the impression that XP gained worked like this:
% that tapping party did of the mob is applied to the party
The XP applied is done in a ratio based off level (IE a level 70, a level 30 and a level 20 are in the party, the 70 soaks most of the xp, the 30 gets some, and the 20 gets less)
The XP then has a multiplier based on the mobs level vs the players level. the XP is about "correct" between -3 and +3 levels. I think there is a limit to where you get XP, and that is your (level/10)+5 below you will give you XP (I think this changes at very low and very high levels).
The XP is then doubled if your rested.
When in a party (2-5 people) there is a party bonus. This appears to be small, but based off your group size.
When in a raid (2-40 people, selected by modifying the party to a "raid") you receive a penalty.
IE: if you had 5 groups that all are separate, that all do 20% of the mobs health, the tapping party will get 20% of the mob's value of XP, and get to loot it.
If you had 5 seperate groups killing their own mob, each character will get about 20% of the mobs XP.
If you had a raid (of 25) that killed 5 mobs, each member would get a little less than 20% of the mobs XP (assuming all things equal).
