Per SE the PT SP bonus is if the party members are all within +- 5 levels of eachother.
Q. What is all this hubbub about a so-called “party bonus”?
A. The party bonus is a feature that increases the amount of skill points awarded to players from combat while in a party. This feature will be in effect so long as the difference in class ranks between all party members is between the range of ±5. In addition, the bonus will be greater the more party members there are.
I read this as: All PT members must be within a 5 level range be is 15-20 or 23-28. for the bonus to kick in.
Q. If I am in a party with someone beyond the ±5 class rank range, will I be getting less skill points than I would be if I were playing solo?
A. No. Rather, the amount of skill points awarded in these two instances would be the same, regardless of whether the player is solo or in a party. If a party bonus is not in effect, the amount of skill points capable of being obtained will be the same.
I take this as if anyone falls outside that narrow range then the bonus is null and void. so if you have a PT mainly of 20-25 and someone dings 26. the bonus is dropped until all the rank 20's become 21.
party members need to be 5 rank max from lowest to highest to get any bonus at all.
If you have a 5 point spread you get the minimum bonus.
if you are all the exact same rank you get the max bonus.
for example you may have ended some fights and seen 23 34 27 25 23 scroll by
in a more optimum grp maybe you saw 115 111 113 121 115 scroll by this is the bonus
I'm certain this is incorrect. You can gain more of a bonus with a larger PT (more people = more bonus) within the +- 5 level range you get not the amount of people the same level. Unless you have proof otherwise. Edited, Oct 30th 2010 3:05pm by SevenLittleChipmunks
