[WOW] - Instance power grinding with lvl 70
I'm looking for calculations and proven information to tell me what the best level makeup is to power grind an alt.
For example.
5 slots
1. Your grinder, lvl 70
2. Your alt, lvl X
3. filler, lvl X +/- A
4. filler, lvl X +/- B
5. filler, lvl X +/- C
What A,B,C makes the most XP for your alt? I've confirmed that your alt has to be higher than everyone but your grinder, but how much higher?
Note: I have also confirmed, you get more xp for a 5-man group with the 3 fillers lower than your alt, then you do with a 4-man group with 2 fillers lower than your alt.
Thanks for your help!
