so basically with a grp of 4 where A refers B refers C refers D, and some stranger lvl 70 E decided to boost them, do they get a triple exp or not?, as far as i read, they wont get triple exp if they are with a member who have some mobs grey
There are 2 answers to this question.

Answer 1. If a mob or quest is GRAY to ANY person in the group there will be no 300% bonus.
Answer 2. It does not work like Answer 1, YET. They want to fix it but have not fixed it yet.

So you will get 3x XP no matter who is in your group, as long as they meet the other requirements, for now.
