Uhh your lack in training EXP would probably be caused by either:
1. Soloing, when partying is best
2. Lower leveled HS,
3. Not dealing as much damage as other mages.
And 10%/30 min = 20%/h, which is terrible, considering your level.
My unmotivated Priestess friend was getting about 30-35%/h while MDTing with me when she was 75. (And I was a Hermit, not a DK)
