I normally stick to Powerslave for the grinding side - as many have said - one fully loaded Eddie like Navigator and the other toons can be whatever you like and are great for levelling up toons. I am doing this form my two kids accounts - buy the XP*2 for gold then load up Powerslave with the AOE Eddie and two lower level toons with decent enough tallies and you rattle through them and get a lot of benefits like souls, upgrade stuff and gold not far off AMOLAD.
