Side question : If i use my lvl 29 priest with the others being 23, in the stockade for ex, will I be penalized in terms of xp?

Yes you will be penalized, lower levels get less, but lower levels need less per level so it evens out. just make sure the mobs arent grey to your low levels and that they arent missing too often.

this is the guestamated formula
CL1 = Character 1 Level, assumed to be the higher level character
CL2 = Character 2 Level
MXP = Solo Mob Experience, as calculated above for CL1
XP1 = MXP * CL1 / (CL1 + CL2), the experience awarded to character 1
XP2 = MXP * CL2 / (CL1 + CL2), the experience awarded to character 2

example
A duo of levels 36 and 34 kill a mob of level 34.
CL1 = 36
CL2 = 34
ML = 34
MXP = 187.500 (the solo XP as calculated for the level 36 char)
XP1 = 187.5 * 36 / 70 = 96.429 (rounds down to 96)
XP2 = 187.5 * 34 / 70 = 91.071 (rounds down to 91)
