Got 2nd place for XP, some 34 XP shy of Tinker's top spot. Prepped EM replaced JJ, so the CA from JJ made up for the bonus XP I got from Imawal (not every mob was killed with Slow bonus XP but since Wetywut is available, the extra XP I got over Tinker shouldn't be that much) - didn't use Imawal for all mobs also.
Yeah, and in general, I am sure Tinker pulled off much better kills (higher level kills).
