With the "Live Help Operator" program dead, and the MP6 perks negligible given the potential active adept population and the weakness of low level MP6 spells, I suggest giving MP6 the LHO spells, at least as long as they remain MP6.
Yes, I'm the only viable candidate to join Syrian as an MP6 but, right now, when I go MP6 I lose training opportunities with non-allied players and get a worthless spell. The extra principle doesn't stick around long enough to build it up. So, MP6 is now more of a curse than a blessing.
